PREFACE 


(1913 EDITION) 

It is the fate of books on estimating for builders that 
they soon become somewhat unreliable, no matter how 
exact they may have been when first published. This is 
due to various reasons,—the continual fluctuations in the 
prices of labor, changes and introduction of new mate¬ 
rials, new methods of construction and style of building. 
Since this book was first published, the changes made in 
the cost of labor and in the selling price of material have 
been wonderful, and it may be said that buildings today 
are fully twenty-eight per cent more costly than they 
were when this book was first published. Recently prices 
have risen so high and at such a rate, that it has been 
found difficult to keep in touch with them. For three 
or four years past, contractors have either made or lost 
a lot of money, for they either have “run up” big prices, 
or, in sticking to conservative figures, have suffered losses 
to a considerable amount. 

While the old figures, as published before the present 
revision, had ceased to be correct, they had, and will con¬ 
tinue to have, the quality of being guides on which cor¬ 
rect, or nearly correct, prices may be based. As nearly 
as I can average up the present costs, they are about 28 
per cent greater than the figures given in the former 
edition. In the present corrected edition, all the figures 
have been overhauled, and changed when necessary to 
suit the current prices. 

'It must not be expected that the prices given herewith

will be correct for all places—they will not. Prices in 
Chicago vary materially from those in Boston, New 
York, Edmonton, New Orleans, and San Francisco, and 
these again differ from the prices prevailing in the cities 
and towns within a hundred miles of these large centers. 
There is not, nor can there ever be, an estimating book 
so arranged that it will give correct figures for all parts 
of the country. Like everything else, “there is no royal 
road to estimating.”

PREFACE 


The man who undertakes to build a book worth any¬ 
thing on estimating the cost of proposed buildings, is 
“up against” a pretty serious proposition. Not that 
such a book cannot be written that will be of great use 
to builders, but because of the ever shifting of prices 
of labor and materials, and the constant changing of 
methods and appliances. Figures that may be all 
right and correct for the work of to-day, may be 
entirely wrong and misleading to-morrow, and this is 
the main objection to works on estimating. 

There are, however, certain rules and constants of 
measurements the estimator may employ when figuring 
up the cost of proposed buildings that may be relied 
upon as being correct, and in this work I have endeav¬ 
ored to show these rules and constants in as clear and 
understandable a manner as I know how, and I think 
my efforts have not been failures. 

After all, the main factor to be employed in the 
make-up of an estimate is experienced judgment. No 
matter how much mathematics a man may be master 
of, if he has not experience in building matters and 
mature judgment to guide him, he can never become 
a reliable estimator. A good judgment may be born 
in a man, but experience can be gained only by a cer¬ 
tain amount of labor and drudgery. As in othei 
departments of science and art, there “is no royal 
road” to estimating, unless it be that which leads to 
guess work and financial disaster; therefore, let me 
press, at the outset, on the minds of all owners of this 

5

PREFACE 


work that an expert estimator can only become so by 
study and by a mastery of all the details that enter 
into the make-up of a building, added to a keen judg¬ 
ment and a comprehensive knowledge of the markets, 
labor, and materials employed on the proposed works. 

Many an honest builder, good mechanic, and clever 
constructionist, has come to grief by taking contracts 
too low, because of his lack of knowledge in estimat¬ 
ing, and thus not only does himself a great wrong, 
but he also disorganizes the whole building business in 
his neighborhood; for if he undertakes to do a certain 
job for a given price, his neighbors will expect to get 
similar work done for similar prices, and rival con¬ 
tractors then strain every nerve to get their estimates 
down to his level, and in doing so inferior materials 
are used, “scamping” is resorted to, and labor is 
crushed and cheapened to meet the conditions. 

In the following work I have made an endeavor to 
place within the reach of every workman of expe¬ 
rience an opportunity of qualifying himself to under¬ 
take the preparing of figures for work, so that he can 
make his tenders within the limits of reason—not 
absurdly high, or ridiculously low—so that only with a 
pen or pencil and this book he may be able to figure 
out and price a set of quantities in short order. 

Great pains have been taken to collect such exact 
information as may be found useful in estimating, 
either in the office or on the building, with the object 
of forming what I believe will prove a valuabe addi¬ 
tion to building literature in other directions than that 
of simply being a price book. 

During the last few years, materials of all kinds, raw 
or finished, have risen in price from 25 to 50 per cent, 
and labor has gone up in nearly the same proportion,

and the end is not vet, and artificial values have been 
created, and this continual fluctuation must always be 
considered when estimating, because no rules can be 
so devised as to be as elastic as prices and mate¬ 
rial men’s quotations. This fact, or facts, only go to 
show that wherever prices are given in books of this 
sort, they should be accepted with salt. Notwith¬ 
standing this, however, the principles of estimating, 
as herein set forth, still hold good in so far as quan 

tities and methods are concerned.

INTRODUCTORY 


Estimating the cost of a proposed building of any 
kind is not of a nature to attract the young workman, 
as it is a dull, dry, and methodical business and only 
the requirements of a sordid and money-making neces¬ 
sity compel the builder to wade through mazes of fig¬ 
ures to attain the desired result. 

If the writer had consulted his own pleasure and 
followed his inclinations he would not have written at 
all, or on a subject more congenial to his taste; but 
from long experience and observation and more or 
less practice, he has witnessed so much ignorance and 
inaptitude on the part of young men who have essayed 
to be builders and contractors that, with the advice of 
his publishers, he has undertaken to prepare this work 
on estimating, because it has been thought that a work 
of the kind may prove useful and of benefit to the 
young man who aspires to be a master builder or a 
contractor, and who may , if he chooses to go to the 
trouble, make himself fairly competent to arrive at 
the cost of any reasonable sized building. It may as 
well be understood at the outset, however, that there 
is no royal road by which eminence as an estimator 
can be attained. No matter what system or method 
may be adopted, correctness can only be reached 
through an avenue of labor and sound judgment. The 
best and most ingenious writers on the subject of esti¬ 
mating have never yet been able to discover or devise 
a method where the cost of a building may be “jumped

at’ at first sight. The system of cubing is, perhaps, 
the easiest of all methods, but is not a system the 
experienced builder would care to follow altogether, 
unless a large margin of profits and contingencies are 
provided for. 

While it will be impossible for me to so prepare this 
work as to be as entertaining as a novel, I will, to 
the best of my abilities, make it as easy to understand 
by the every-day workman as it possibly can be. 

Estimating is the most difficult task the builder has 
to deal with, and too much care cannot be taken, even 
if the quantities are supplied, if a correct tender is 
wanted. Many who tender make up their prices in a 
haphazard manner, often depending on trade cata¬ 
logues, price lists or newspaper quotations for data, 
using their judgment, whether experienced or not, and 
without a full or even a fair knowledge of the scientific 
methods which underlie the proper formulating of a 
true estimate. Prices which enable successful con¬ 
tractors to calculate values for themselves are obtained 
by dissecting, taking asunder and examining the 
various elements that go to make them up, the com¬ 
plete result being shown in a final bill of quantities, 
labor and other costs. 

It will be impossible to make this work a mere 
hand-book of builders’ prices, as what may be the ruling 
price of labor or material to-day may be very much 
different to-morrow, as in these days of continual 
change there can be no such thing as “constants” in 
prices. I can give quantities, however, and describe 
the proper methods of obtaining them, and can convey 
to the student the principles upon which correct esti¬ 
mating is based, and offer here and there the prices of 
labor as nozv current in the larger cities, not to be fol*

lowed, but simply to give an idea of the cost of various 
kinds of work when no other data is available. 

No man can be a successful contractor who does not 
attend strictly to his bookkeeping, so that he can tell 
in a moment, by reference to his books, the exact 
amount of profit or loss on the various jobs of work he 
has completed. This i$ important, inasmuch as the 
mistakes in estimating may be traced to their source, 
and thus be avoided when similar jobs are being figured 
on; and much trouble and disappointment may be 
avoided by having the accounts on every job itemized 
and kept in proper order. I will have more to say on 
this subject later on. 

All estimates should be retained, properly labeled, 
and put in some place where they can be found when 
required, whether the work for which they were pre¬ 
pared is secured or no f , for they will often prove of 
great service for future reference; and the estimator 
should make a note of each particular on which he may 
have priced too high or too low, if his tender is not 
accepted. If the work is secured, the cost of each par¬ 
ticular item in the building should be compared with 
the estimated price, and a note should be made on the 
margin of the original estimate showing the discrep¬ 
ancy, if any, between estimated and actual price. A 
correct account of all labor, how employed, should 
also be kept, so that the contractor may know from 
actual facts exactly what a piece of work costs, or the 
number of days or hours it required to perform such 
and such work, also amount and cost of materials on 
the same work; then, in preparing other estimates, he 
will have something tangible to base his figures on. 
It is better to estimate on days or hours for time, and 
on quantities for materials, because of the continual 


HODGSON’S ESTIMATOR 


fluctuations in price of labor and materials of all kinds. 
If it takes 2 £ days, of 9 hours each, to execute a piece 
of work, the figuring on this is quite simple, for all we 
have to do is to multiply the number of hours by the 
price per hour for labor; suppose this to be 30 cents 
an hour, then we have 22% x 30 = G75. That is, in 2£ 
days, at 9 hours per day, we get 22% hours at 30 cents 
per hour, which will make 675 cents, or Of dollars. 
Quantities may be figured in a similar manner. If the 
work requires 150 feet of material, then charge that at 
current rates, whatever these maybe; then add cost of 
labor and material together, and you have the bare 
cost of the work. To these, of course, must be added 
cartage, profit and any other materials that have been 
employed on the work, such as nails, screws, glue, 
paint, or anything else. By following this course, a 
record of all work done and estimated for will always 
be at hand, and it is surprising how much the labor of 
estimating may be reduced by a strict adherence to 
this system, as a comparison with work done and work 
to do may be made in a few minutes, and the differ¬ 
ence in prices of labor then and now adjusted so that 
no loss will occur to the contractor. 

The variations in tenders for the same work are often 
surprising. I have seen estimates, particularly in car¬ 
penter’s and joiner’s work, run up to as much as 50 per 
cent above the tenders of competing contractors, yet 
the lowest bidder made money. Competent esti¬ 
mators never make such wide errors as this, though 
often they do not keep close to the wind; and while 
mistakes will continue to be made, even by the very 
best estimators, by omissions, “doubling up,” and 
using wrong dimensions, the mistakes may be nar¬ 
rowed down to a very small area if system, care and 


AND CONTRACTOR’S GUIDE 


13 


judgment be exercised when the estimates are made. 
It will be the object of this little volume to narrow this 
area of error to the smallest possible limits, and to 
show the estimator how to avoid grievous errors and 
make his estimates more satisfactory and reliable. 

CATALOGUES AND PRICE LISTS 

No builder’s office can be well equipped except it 
contains the latest catalogues and price lists available, 
for on these the estimator must, to some extent, be 
dependent in his figuring on the cost of most of the 
material that goes in the work. Bricks, stone, lime, 
cement, lumber, hardware, and factory-made stuff 
may have their prices approximated from these publi¬ 
cations, but the shrewd estimator, while making use of 
these aids, does not rely upon them for serious pricing. 
They help considerably, as they contain a lot of con¬ 
densed information regarding prices and building; 
but they are not always to be depended upon, as they 
are not always compiled in a scientific way. For 
example, some of the prices include trade discount, 
some do not, while others are merely the ordinary 
list prices of merchants’ catalogues. The discount in 
itself largely varies, and there are two, and often 
more, discounts—a trade discount and a cash dis¬ 
count—and other mysterious discounts, such as 30% 
and 5%, which means 30 per cent off and 5 per cent 
off the balance; and again, the percentages are not uni¬ 
form; one merchant may have one discount, another 
another, so in all cases it is best to get prices and dis¬ 
counts direct from the merchant wherever possible. 
The diversities in discounts are innumerable, and it is 
the estimator’s duty to get definite information as to 


14 


HODGSON’S ESTIMATOR 


prices and discounts as prevailing in the locality where 
the work is to be done. 

Builders’ prices are broadly made up of two divi¬ 
sions, labor and material, to which may be added a 
third, namely, profit. The cost of labor and material 
vary from time to time, and from place to place, and 
do not fluctuate similarly. Sometimes labor may be 
high and materials low in price, and at other times 
materials may be high and labor low, so that no given 
rules can be formed to meet these conditions and be 
constant, and this fact rules price-books out of the race 
of accuracy for any length of time. Such things as 
closeness or slackness of supervision, misunderstand¬ 
ings as to quality of workmanship or materials, worry¬ 
ing by the architect, delay in furnishing detail draw¬ 
ings, differences in locality and site, frost and bad 
weather, sudden and unexpected rises and falls in the 
market, etc., will all help to alter the conditions of 
profit or loss for the contractor, and the extent of 
which is almost impossible to measure. 

When, however, the contractor has worked cut a 
series of prices for himself, to suit both time and 
locality, he must be on the alert for parallel cases to 
avoid the great labor involved in making calculations 
afresh every time a new estimate is required. In fact, 
he should carefully prepare a sort of price-book for 
himself, suitable to the conditions, and so arranged 
that it can be revised from time to time. Thus a con¬ 
sistency in pricing would result, which is of consider¬ 
able importance. 

As already stated, the builder will be confronted 
with several grades of discounts, and among them will 
be a cash discount. This may be more or less or any¬ 
where within the limits of from 2 to 5 per cent, and it 


AND CONTRACTOR’S GUIDE 15 

should be the aim of the contractor to get the best dis¬ 
counts to be had, providing the materials or goods are 
up to the standard demanded by the specifications. 
Sometimes it may happen that on special goods or 
some particular make of hardware or other items, no 
discounts are allowed. This, however, can only hap¬ 
pen when a dealer has the sole control of these special 
goods, or when there is a scarcity of them in the 
market, or when a sudden demand for them arises. 
These conditions, however, seldom or never occur, so 
they may hardly be considered. In the practice of a 
shrewd contractor, the question of discounts enters 
largely into the make-up of an estimate, particularly 
where close competition is likely to be met with. 

The question of profit is one that must be well con¬ 
sidered when estimating; 10 per cent is the least 
amount a builder can accept, exclusive of established 
charges, and this should be added to each individual 
price, and no provision should, under ordinary condi¬ 
tions, be made for any trade discounts, as these are 
expected to swell the profits. Some estimators when 
pricing bills of quantities prefer to add a lump sum as 
profit at the end of a bill. This, however, is not a 
good thing to do, as it gives no correct method of 
knowing what the profits are. 

For wood or materials on small jobs, where both are 
limited, the profit should be higher, as the total 
expenditure in such a case is much more in proportion; 
therefore the percentage of profit should never be less 
than 15 per cent on work costing up to $2,500, but 
above this amount a smaller percentage would perhaps 
be sufficient. 

The large contractor, who may perhaps own his own 
brickyard, quarry or factory, with extensive premises 


HODGSON’S ESTIMATOR 


i6 

and rapid-working labor appliances of all kinds, can 
naturally turn out work cheaper and more expeditiously 
and at a greater profit to himself than the small con¬ 
tractor who possesses none of these appliances and 
aids. Often the latter, in order to save himself from 
loss, is obliged to scamp the work and use inferior 
materials, which he can frequently “get in” without the 
architect being able to detect it; he is often obliged to 
do this in order to keep himself afloat. My advice in 
cases of this kind is, that the lower contractor should 
confine himself to certain prices—that will pay him — 
and if he cannot win the work for these prices he had 
better leave the work for the larger contractors, and 
thereby preserve his reputation and his money. The 
small contractor can always find plenty of work to do 
if he but gets a good name for doing his work well 
and according to specification. 

Where there are dozens of doors made from one 
pattern, as many window frames and sashes, and hun¬ 
dreds of feet of mouldings in wood or stone of one 
shape and size, they can be rattled out by machinery in 
short order and at a comparatively low cost, and this 
is an item the estimator must consider, as it will aid 
materially in keeping down the total amount of tender; 
in any case, however, experience and judgment in 
such matters are required before a definite amount can 
be decided upon. 

With reference to terms of payment, it is always 
better that the contiactor gets his money often, as it 
enables him to push his work with greater vigor, and 
gives him a chance of making the best cash discounts 
when purchasing materials, and, on these several 
accounts, he will be able to make a lower bid for the 
. work than otherwise. The reserve to be deducted 


AND CONTRACTOR’S GUIDE 


17 


from each payment should never exceed 25 per cent, 
which is considered ample to cover any liens of work¬ 
men or material men and safeguard the interests of the 
owner. There are certain fixed charges or provisions 
in contracting that must not be overlooked. These 
consist of salaries, depreciation of plant, tools, 
machinery, rent of premises, lights, water, and inter¬ 
est in capital invested, of which the new work must 
pay its proportional share, and these charges should 
be kept separate and added to the estimate along with 
the percentage of profit. Such charges are commonly 
placed at G per cent interest on capital invested, and 3 
per cent for depreciation of plant, etc. Sometimes 
they are classed in two categories: G per cent on work 
done on the building, and 8 per cent on work done in 
the contractor’s factory or shops. These percentages, 
however, are somewhat arbitrary, and should be the 
result rather of experience and good judgment than 
any fixed rules, and the foregoing remarks are offered 
rather as reminders that some allowances must be 
made for each item when estimating, otherwise they 
might be overlooked. 

The question of transportation is one also that enters 
largely into the cost of work. If the works are situ¬ 
ated nearby the office and establishment of the con¬ 
tractor, the question will not be so formidable as when 
the work is some distance away, as the greater part of 
the material will very likely be near the ground and 
may only require handling and teaming once; but 
where the work is at a distance, the expense of getting 
the material on the ground will necessarily be much 
greater. When conditions will admit of it, it is always 
better and cheaper to have material shipped by boat 
than by rail, or long hauls by team, and the estimator 


i8 


HODGSON’S ESTIMATOR 


should make himself familiar with all the ways of 
communication to the spot where the building or build¬ 
ings are to be erected, and should get a schedule of 
rates from all the lines running to that point. A good 
idea is to get a map of the district which shows all the 
railway and water communication; then the shortest 
and best routes can be chosen, providing the rates are 
satisfactory. As I stated before, it is much better, 
when it can be done, to ship by water than by land, as 
because of the absence of vibration, fine work will 
be less likely to be injured or scratched during 
transit, and, as a rule, rates are always lower by water 
than by land. The average rate for the shipment of 
goods in this country is about 1} cents per mile for 
short hauls, and something less for long hauls.* Rates, 
however, vary with the different roads and at different 
times, the highest rates being in winter, in the north, 
when the waterways are frozen up. Classification, 
also, has something to do with regulating rates. All 
goods should be insured or shipped at the carrier’s 
risk, then losses or damages will be covered. If goods 
have to be packed, or put up in crates or boxes, at 
least 15 per cent should be allowed for this work and 
material, and should be charged on the special goods 
boxed or crated only, but added to the estimates. 

Goods sent at carrier's risk that get damaged, should 
be returned by the same carriers free of cost, and 
when repaired or renewed should be delivered at the 
point where first destined, at the cost only of the first 
shipment of the same goods. That is, the shipper 
should pay for one shipment only. 

Where a quantity of goods of a similar kind is 
required, a special quotation should be given the con-

tractor by the dealer, and this should never be over¬ 
looked, for it is not likely that it will be given if not 
applied for. 

Trade discounts, as a rule, are not publicly stated in 
trade catalogues or circulars; they can be obtained 
only on private application. Their amounts greatly 
depend on the quantity of goods ordered, and the 
larger the order the larger the percentage given. 

The foregoing remarks are offered as a sort of pre¬ 
liminary and should be well considered by the intend¬ 
ing estimator, as they contain much that will tend to 
smooth the way towards accuracy in making up a 
tender, and, if followed attentively, will enable the 
estimator, along with the rules that follow, to get at a 
result that will be nearly correct and satisfactory. 


SYSTEM IN ESTIMATING 

The estimator should follow some well-defined sys¬ 
tem in his work, in order that he may know he has not 
overlooked anything, for one of the dangers is that of 
omission. To overlook the roof—as I have known 
one instance of the kind—the floors, the doors, or any¬ 
thing else, is a serious matter, and in order to prevent 
this as much as possible I have prepared a list of items 
which I give further on, and which may be called a 
“Tickler” or a “Reminder” of what will be required 
to consider when making an estimate of a building 
complete. 

When erecting a structure of any kind, work should 
commence at the earth, so the first thing estimated, 
following the same rule, should be the excavations for 
cellar, drainage, foundations, trenches, and other simi¬ 
lar work, then the preparing and the laying of the 


20 


HODGSON’S ESTIMATOR 


foundations, whether of stone, concrete, or brick; and 
the same order should be followed throughout the 
whole building, until the whole is fully completed, 
from turning the first shovelful of earth until the last 
piece of finished work is put in place. 

The following items will remind the estimator of the 
things to be figured on as he works his way upwards:

While the foregoing does not pretend to give all the 
items that may be required, it offers to the estimator 
some hints as to what is required, in a general way, for 
domestic buildings. For factories, stables, barns, ware¬ 
houses, public buildings, churches, schools, railway 
stations, and similar work, a more elaborate list would 
be required, but the estimator should be able to find a.i 
the items in the specifications prepared for the work 
under consideration, and if he is thorough he will add 


AND CONTRACTOR’S GUIDE 


*7 

to the list as given above such items, with their cost, 
as he goes over them when figuring. 

DIFFERENT METHODS OF ESTIMATING 

It is said there are not less than five different 
methods of estimating. Four of these are uncertain, 
but answer for the purpose of getting an approximate 
cost of some proposed work, and are chiefly made 
use of by architects and engineers to give their clients 
an idea of cost before going into actual building opera¬ 
tions. The fifth method, which is the only reliable 
method, is the taking out of exact quantities item by 
item. 

The first of these methods is the estimating by the 
cost per cubic foot of similar buildings. It is the best 
known method, and most usually adopted because of 
its general convenience. The dimensions are best 
taken by measuring the length and breadth from out to 
out of walls, and the height from half foundation to half¬ 
way up roof. The cubic contents, then obtained, are 
multiplied by the price per foot cube of some similar 
building. Sometimes the height is measured from the 
bottom of footings to half-way up the roof. Cheaper 
attached structures, such as annexed stables, sheds, 
etc., should be kept separate and priced lower; while 
more ornamental portions, like towers and porches, 
jhould be valued at a higher rate than the main block. 
Small buildings cost more in proportion than large 
ones of the same type. 

This cubing system is open to some objections. The 
lumping together of solids and voids at one rate is cer¬ 
tainly not scientific, for the same class of buildings 
may be divided into many rooms with numerous 
mternal solids in the shape of walls, etc., between; 


28 


HODGSON’S ESTIMATOR 


while another may have comparatively few chambers, 
creating much empty space. In fact, the proportion 
of voids to the solid structure is not a fixed quantity, 
so that the price per cubic foot can never be exactly 
regulated. This method requires a large experience 
and a nicety in pricing which the estimator cannot 
always possess. The description and quality of mate¬ 
rials and workmanship, too, are seldom the same; 
neither are the conditions of contract, and these varia¬ 
tions are frequently overlooked when a certain rate per 
cubic foot is assumed. 

A second method is to take out rough quantities and 
price the items as the estimate proceeds. In this 
case the quantities of materials and workmanship are 
ascertained from the drawings in a broad and compre¬ 
hensive manner, the work being concentrated as much 
as possible into a few specific items and afterwards 
priced accordingly. Although this course is perhaps 
less generally used than any other for estimating pur¬ 
poses, yet it is one of the most reliable methods that 
can be adopted when time and circumstances do not 
admit of detailed quantities and prices. The fact that 
such a method is not more frequently used is probably 
due in a great measure to the want of a readily access¬ 
ible table of prices for the different groups of materials 
and labor. Slightly more time is also required for this 
purpose than when the cost is arrived at by the cubic 
contents or any other methods except by detail pricing. 
The final result, however, is nearer the truth than it 
would be by cubing. In estimating by this method it 
will be well to add io per cent for contingencies. 

When rough quantities are being taken for an approx¬ 
imate estimate, it is desirable that the various descrip¬ 
tions of materials and workmanship should be grouped 


AND CONTRACTOR'S GUIDE 


*9 

together so as to form as few separate items as pos¬ 
sible; also, in all cases where it can be clone, the items 
should be priced as per square of ioo feet superficial, 
for the sake of uniformity and convenience. 

The walls should be classed according to their mate¬ 
rials and thickness, at the same time stating whether 
external or internal. Each item should include a 1 1 
necessary digging, footings, doors, windows, and fin¬ 
ishings of wall surfaces, such as plastering, facings to 
external walls, etc., so that the item, and consequently 
the price, shall be inclusive of everything that apper¬ 
tains to the various enclosures or divisions of the 
building. For this purpose the superficial area of the 
walls should be obtained by taking the extreme length 
of each wall by the height from the bottom of the 
footings to the top of the eaves, in cases where the 
thickness of the wall is the same throughout. Should 
the wall vary in thickness, either in its length or 
height, each portion should be measured separately. 
No deductions must be made for door, window or 
other openings. Bay windows, chimneys and other 
additions of a like nature should be numbered and 
priced according to their materials and workmanship. 

The floors may be dealt with in a manner similar to 
that described for the walls. The ground and upper 
floors must be kept separate, and classed according to 
^he materials and finishings required. The item for 
wood floors on the ground floor to include sleepers, 
dwarf walls, joists, boarding, hearths, etc., together 
with a layer of concrete on brick rubbish over the whole 
area, and all necessary digging for same. Similarly, 
concrete or other floors will include all materials, 
labor, and finished surfaces that may be required. 
The upper floors to be treated in a similar manner. 


30 


HODGSON’S ESTIMATOR 


The item to include all joists, boarding, hearths, ceil¬ 
ings, cornices, and whitening or coloring the same. 
The roof coverings to be measured on the slope, the 
item being inclusive of roof trusses, rafters, boarding, 
shingling, slating or other covering, leadwork, eave- 
gutters, down pipes, etc. Ceiling joists, ceilings and 
whitening or coloring to ceilings will also be included 
in the same items here required. 

Drains, gas and water mains, electric wiring, and 
items of a similar nature, should be taken at per foot 
or per yard run, according to sizes, including all neces¬ 
sary digging, laying, filling, and removal of surplus 
materials. Manholes, disconnecting pits, etc., to be 
numbered and priced according to size and average 
depth. 

Staircases to be taken at per step, or per foot in 
height, classed according to their widths, and the 
nature of the materials and finishings. Gas and water 
fittings to be priced at per light or per tap, including 
all service-pieces from mains, digging, etc. 

Fitments or furnishings generally, such as cupboards, 
baths, sink, w. c.’s, ranges, grates, mantels, etc., are 
numbered and priced according to the class of fitments, 
material and finishings required. 

A series of average items and approximate prices 
adapted to this method of estimating, may be found in 
this work in some of the tables, rules and memoranda 
that follow. 

The third method of estimating is by the square of 
ioo feet, which, under some circumstances, is quite 
convenient for obtaining approximate cost. Its use is 
principally confined to one-story buildings, such as 
sheds, stores, schools, churches, chapels, stables, rau 
way stations, bungalows and similar buildings. It mav. 


AND CONTRACTOR’S GUIDE 


31 


however, be used for buildings two or more stories in 
height; but a considerable amount of discrimination 
and care must be exercised in order that the final 
result may be relied upon. 

The superficial area is obtained by taking the dimen¬ 
sions from out to out of walls at the ground level, so 
as to include any projection of the plinth or other off¬ 
set which frequently occurs at the base of a building. 
The result is commonly called the plinth area of the 
building. Where the materials, workmanship, or 
height of building or floor varies, each description or 
height must be kept distinct in order that they may be 
separately priced. 

In case of one-story buildings, the price per square 
includes foundations, walls, floor, roof, and all finish¬ 
ings. Occasionally data is at hand by which build¬ 
ings comprising two or more stories, such as ware¬ 
houses, etc., may be priced in the same way, the 
price per square of “plinth area” including founda¬ 
tions, walls, ground and upper floors, roof, etc., all 
complete. 

For general purposes, however, it is more conven 
ient to separate the different floors of buildings ol 
more than one story in height and price each floor 
accordingly. 

When this course is adopted for two or more stories, 
the ground floor is taken to include foundations, floor, 
walls, ceiling, and all finishings. Upper floor includes 
floor-joists, flooring, walls, ^eilings, finishings, etc., 
whilst the top floor includes the roof covering in 
addition. 

Sometimes two-story buildings have both floors 
priced all the same rate, as it is found that the average 
cost of the ground floor, including the foundations, is 


32 


HODGSON’S ESTIMATOR 


about the same as that of the first floor, which includes 
the roof covering. 

It is also useful to remember that the floor area of a 
certain description of buildings affords some indication 
of the amount of accommodation provided. For class 
rooms in schools, the floor area accommodates from 
seven to ten scholars per square, being an allowance 
of fourteen to ten superficial feet per child. 

Ordinary churches accommodate from nine to twelve 
persons per square, corresponding to a total floor area 
of eleven to eight feet superficial per sitting respect¬ 
ively. In mission churches, etc., the floor space fre¬ 
quently averages about seven feet per sitting, or at the 
rate of fourteen persons per square. These figures 
include the floor area which is necessarily absorbed by 
aisles, pulpit, choir, vestry, sanctuary, etc. 

The actual amount of floor space required per person 
for seating accommodation in churches is from 4J feet 
to 5J feet, superficial. 

Pews, or sittings, in churches are usually spaced 
from 34 to 36 inches apart (measuring from back to 
back of seats), whilst the average length of seat 
required per person is from 20 to 22 inches. 

A fourth method of estimating is by unit of accom¬ 
modation, and in practice it is found that for certain 
descriptions of buildings or works, constructed under 
normal conditions, the cost of such buildings or works 
varies (within certain limits) in a direct ratio to some 
known unit of accommodation or requirements. 

For such buildings as hospitals, schools, churches, 
factories, etc., the cost can be approximately given, if 
the number of patients, children, etc., required to be 
accommodated is known. On occasions when time 
will not admit of even a sketch of the proposal being 


AND CONTRACTOR’S GUIDE 


33 


made, this method affords oftentimes the only ready 
means of ascertaining the approximate cost. Simi¬ 
larly, for certain minor accessories where the cost of 
materials and construction varies but slightly for units 
of the same class, as in a range of latrines, etc., the 
approximate cost can be easily determined in the 
same way. Data for this method of estimating will be 
found in the rules I give in this work. 

The fifth, and most correct, method of estimating is 
by taking out accurate quantities of materials and 
items of all kinds and pricing them as the figures are 
obtained, and then adding the cost of labor to each 
item. This may be called a “detailed bill of quan¬ 
tities.” This method, because of its entailing so much 
labor, should be adopted only when it is intended to 
carry out the work and when a tender is sent in or 
submitted for work about to be gone on with. It is 
very laborious, and necessitates great skill and a 
thorough knowledge of building construction, and par¬ 
ticularly of the work to be tendered for, so that the 
subject is somewhat difficult for young hands to deal 
with. The system should be divided into three parts 
or processes, namely, “Taking off,” “Abstracting,'’ 
and “Billing,” the last portion showing the prices. 
In this method a full set of drawings of the work and 
copious specifications are necessary, so that the esti¬ 
mator can take the dimensions from one and quality 
of material and character of work from the other. The 
cost of the various descriptions of material and work¬ 
manship are then priced in accordance with the current 
rates obtained in the locality where the work is to be 
carried out. This method takes time and much labor, 
but it has the advantage of being correct, or nearly so, 
if the work is honestly and faithfully performed. In 


34 


HODGSON’S ESTIMATOR 


fact, it is the only method a young contractor should 
use when commencing business. After years of expe¬ 
rience and observation as a builder and contractor, 
cubing, or one or other of the quick methods, may be 
made use of under certain conditions, where the con¬ 
tractor knows what he is about. My advice, however, 
is to stick to the old and reliable method of estimating 
by items. It takes time, but the time and labor are 
well invested. 

The young estimator must necessarily have a fair 
knowledge of arithmetic, particularly that branch of it 
termed mensuration, before he can hope to become an 
expert; indeed, it will be impossible for him to become 
an expert unless he is good at figures and has some 
knowledge of geometry. In order to put him in a 
position to be able to wrestle with problems that are 
sure to crop up in estimating, I deem it expedient to 
arm him with rules and methods for obtaining areas, 
dimensions, and contents of all sorts of figures or solids 
he may meet with. 

It is but just to say that these rules and methods can 
be found in many works, but it has been thought expe¬ 
dient to reproduce them here, so that the student may 
have them at hand when making use of this work for 
study or for practical estimating. The rules and prob¬ 
lems are selected chiefly from educational works, and 
the tables have been prepared by competent author¬ 
ities, and have been examined and corrected, where 
necessary, and made suitable to the work in hand. 

It is presumed, at the outset, that the reader has 
some knowledge of arithmetic and is therefore able to 
follow without difficulty the problems that follow, 
which, after all, should offer no serious obstruction to 
a thorough knowledge of their qualities.

MENSURATION OE SUPERFICIES 

Mensuration is that branch of mathematics by which 
we ascertain the contents or superficial areas, and the 
extension, solidities, and capacities of bodies. 

The area , or superficial contents of any figure, is the 
measure of its surface, or the space contained within 
the bounds of that surface, without any regard to 
thickness. 

In calculating the area, or the contents of any plane 
figure, some particular portion of surface is fixed upon 
as the measuring unit , with which the figure is to be 
compared. 

This is commonly a square , the side of which is the 
unit of length, being an inch, or a foot , or a yard, or any 
other fixed quantity, according to the measure peculiar 
to different artists; and the area or contents of any 
figure is computed by the number of those squares con¬ 
tained in that figure. 

For the same reason, determining the quantity of 
surface in a figure is called squaring it; that is, deter¬ 
mining the square or number of squares to which it 
is equal. 

In order to form correct estimates of the extent of 
surfaces and solids, various rules have been adopted, 
most of which, the most valuable and useful in prac¬ 
tice, will be found accompanying their respective 
problems in the following treatise, and with which the 
mechanic may speedily perform all the calculations 
that ordinarily occur in the practical details of his 
business.

DEFINITIONS 

The following definitions, which are similar in sub¬ 
stance to those found in Euclid, are here inserted for 
the convenience of reference. 

I. Four-sided figures are variously named, according 
to their relative position and length of their sides. 

1. A line is length, without breadth 01 thickness. 

2. Parallel lines are always at the same perpendicular 
distance and they never meet, though ever so far 
produced. 

3. An angle is the inclination or opening of two lines, 
having different directions, and meeting in a point. 

4. A parallelogram has its opposite sides parallel and 
equal. 

5. A rectangle , or right parallelogram, has its opposite 
sides equal, and all its angles right angles. 

6. A square is a figure whose sides are of equal 
length, and all its angles right angles. 

7. A rhomboid has its opposite sides equal, and its 
angles oblique. 

8. A rhombus is an equilateral rhomboid, having all 
its sides equal, but its angles oblique. 

9. A trapezoid is a quadrilateral figure, having only 
two of its sides parallel. 

10. A trapezimn is an irregular figure, of four unequal 
sides and angles. 

11. When figures have more than four sides, they are 
classed under the head of Polygo?is. 

These again are either regular or irregular, according 
as their sides and angles are equal or unequal, and 
they are named from their number of sides or angles. 
Thus, a regular polygon has all its sides and angles 
equal.

III. A figure of three sides and angles is called a 
triangle , and receives particular denominations from 
the relations of its sides and angles. 

1. An equilateral triangle is that whose three sides are 
equal. 

2. The height of a triangle is the length of a perpen¬ 
dicular drawn from one of the angles to the opposite 
side. 

3. An isosceles triangle is that which has only two 
sides equal. 

4. The height of a four-sided figure is the perpendic¬ 
ular distance between two of its parallel sides. 

OF FOUR-SIDED FIGURES 

Problem I.—To find the area of a four-sided figure, 
whether it be a parallelogram, square, rhombus, or 
rhomboid.

pendicular height, and the product will be the area.

Note. The fundamental problem, in the mensuration of super¬ 
ficies, is the very simple one of determining the area of a right 
parallelogram. The contents of other figures may readily be 
obtained by finding parallelograms which are equal to them. 


d 


Take any parallelogram, a b c d , and divide each of 

% 

its sides, respectively, into as many equal parts as are 
expressed by the number of times they contain the 
linear measuring unit, and let all the opposite points of 
division be connected by right lines. 
Then it is evident that these lines divide 
the parallelogram into a number of 
squares, each equal to the superficial 
measuring unit, and that the number of 
these squares, or the area of the figure, 
is equal to the number of linear measuring units in the 
length, repeated as often as there are linear measuring 
units in the breadth or height; that is, equal to the 
length multiplied by the height, which is the rule . 


OF TRIANGLES

Problem IV.—To find the area of a trapezoid. 

Rule .—Multiply the sum of the two parallel sides by 
the perpendicular distance between them, and half the

Example /.—Required the area of the trapezoid, 
abed , having given a b = 321.51 
feet, d c= 214.24 feet, and whose- 
height is 171.16 feet. 

We first find the sum of Ihe sides, a 
and then multiply it by the perpendicular height; after 
which, we divide the product by 2 for the area. 

321.514-214.24=535.75=the sum of the parallel sides. 

Then, 535.75X171.16=91698.97. 

And, 91698.97-^2=45849.485. Ans. 


OF REGULAR POLYGONS 

Problem V.—To find the area of a regular polygon, 
or any regular figure. 

Rule 1 .—Multiply one of its sides into half its per¬ 
pendicular distance from the center, and this product 
into the number of sides. 

It is evident, on inspection, that a regular polygon 
contains as many equal triangles as the figure has sides. 

Thus, the adjoining hexagon has six triangles, each 
equal to a b c. Now, the area of a b c is equal to the 
product of the side a b into 4 of c d. The area of the 

whole, therefore, is equal to this prod¬ 
uct multiplied into the number of sides. 

Example. —1. Required the area of a 
regular hexagon, each of whose sides, 
a b , etc., is 45 feet, and the perpendicu- 
d 0 lar, c d , 24 feet.

Now, since the areas of similar polygons are to each 
other as the squares of their homologous sides, if the 
square of a side of a polygon be multiplied by the 

multiplier of the like figure, the product will be the 
area sought. And hence we have,

To find the area of a regular polygon, when the side 
only is given. 

Rule .—Multiply the square of the side by the multi¬ 
plier opposite the name of the polygon in the above 
table, and the product will be the area.

ADDITIONAL USE OF THE ABOVE TABLE 

The third and fourth columns of the table will 
greatly facilitate the construction of those figures with 
the aid of the sector. Thus, if it is required to describe 
an octagon , opposite to it, in the third column, is 45; 
then with the chord of GO on the sector as radius, 
describe a circle, taking the length 45 on the same line 
of the sector; mark this distance off on the circum¬ 
ference, which, being repeated around the circle, will 
give the points of the side. 

The fourth column gives the angle which any two 
adjoining sides of the respective figures make with 
each other. 

* Take the length of a perpendicular drawn from the 
center of one of the sides of a polygon, and multiply 
this by the numbers in column A; the product will be 
the radius of the circle that contains the figure. 

The radius of a circle, multiplied by the number in 
column B, will give the length of the side of the cor¬ 
responding figure which that circle will contain. The 
length of the side of a polygon, multiplied by the cor¬ 
responding number in the column C, will give the 
radius of the circumscribing circle.

the truth. 


OF THE CIRCLE AND ITS PARTS 
DEFINITIONS 

1. A circle is a plane figuie, bounded by a curved 
line, called the circumference, every part of which is 
equally distant from a certain point within, called the 
center. 

2. A diameter of a circle is a straight line, passing 
through the center, and terminating at the circum¬ 
ference. 

3. A radius or semi-diameter is a straight line, extend¬ 
ing from the center to the circumference. 

4. A semi-circle is one half of the circumference. 

5. A quadrant is one quarter of the circumference. 

G. An arc is any portion of the circumference. 

7. A chord is a straight line, which joins the two 
extremes of an arc. 

8. A circidar segment is the space contained between 
an arc and its chord. The chord is sometimes called 
the base of the segment. The height of the segment is 
the perpendicular from the middle of the base to the 
arc. 

9. A circular sector is the space contained between 
an arc and the two radii, drawn from the extremes of 
the arc. 

10. A circular zone is the space contained between 
two parallel chords which form its bases. 

11. A circidar ring is the space between the circum¬ 
ferences of two concentric circles.

HODGSON’S ESTIMATOR 


12. A lune or crescent is the space between two cir* 
cular arcs, which intersect each other. 

13. An ellipse or oval is a curve line, which returns 
into itself like a circle, but has two diameters of 
unequal length, the longest of which is called the 
transverse, and the shortest the conjugate axis. 

Problem I.—To find the circumference of a circle 
when the diameter is given. 

Rule .—Multiply the diameter Hv 3.1410, and the 
product will be the circumference Or, multiply the 
diameter by 22, and divide the product by 7. Or, 
multiply the diameter by 355, and divide the product 
by 113. 

Note. —The latter rule is a little more accurate than any other 
expressed in small numbers. 


Example. —1 . What is the circum¬ 
ference of a circle whose diameter, 
a b , is 40 feet? 

40X3.1416=125.66. Ans. 

Example. —2. Required the circum¬ 
ference of a circle whose diameter is 73£. 

Ans. 231.6922. 



Note. —See Table of Circumferences of Circles. 


Problem II.—To find the diameter of a circle when 
the circumference is given. 

Rule. —Divide the circumference by 3.1410, and the 
quotient will be the diameter. Or, multiply the cir¬ 
cumference by 7, and divide the product by 22. 

Example. —The circumference of a circle is 69.115 
yards: what is the diameter? 

69.1 15-t- 3.1416=22 yards. 

The same result may be obtained more conveniently, 
by exchanging the divisor , 3.1416, for a multiplier , 



AND CONTRACTOR’S GUIDE 


47 


which will give the same answer, for, in the propor¬ 
tion 3.1416 :1 ::Circ. : Diam., the fourth term may be 
directly found by dividing the second by the first, and 
multiplying the quotient into the third. Thus, 
1-4-3.1416=0.31831. Therefore, if the circumference 
of any circle be multiplied by the decimal .31831, the 
product will be the diameter. 

In many cases there will be a decided saving of labor 
by exchanging the divisor for a multiplier, as will be 
seen in the following example: 

Example. —What is the diameter of a circle whose 
circumference is 50? 

50X.31831=15.91550. 

Note. —As multiplication is more easily performed than divi¬ 
sion, this last method is decidedly the more preferable. 

Problem III.—To find the area of a circle when the 
diameter and circumference are both known. 

Ride. —Multiply the square of the diameter by .7854. 
Or, the square of the circumference by .07958. Or, 
multiply the circumference by the. diameter, and 
divide the product by 4; in either case the product 
will be the area. 

Example. —1. Required the number of square inches 
in a piston whose diameter is 12£ inches. 

12$ 2 =12.5X 12.5=156.25, and 156.25X.7854=122.71 sq. in. Ans. 

2. The piston of the railroad engine Boston is 15 
inches diameter: how many square inches does it con¬ 
tain? 176.71. Ans. 

Note. - The reason of this rule will appear by considering that 
if the circumference of a circle be 1, the diameter will=0.31831 
(Prob. II), and 1 of this diameter into the circumference is 0.7958 
=area. (See Table of Areas of Circles.) 

Problem IV.—I. To find the length of an arc of a 



48

circle, when eitner the number of degrees which it 
contains, or the radius, chord, and height are given. 

Rule. —Multiply the number of degrees in the arc by 
the decimal .01745, and that product by the radius of 
the circle. Or, from 8 times the chord of half the arc, 
subtract the chord of the whole arc, and ^ of the 
remainder will be the length of the arc, nearly. Or, 
as 3 is to the number of degrees in the arc, so is .05236 
times the radius to its length. 

Example. —1. What is the length of an arc of 40 
degrees, in a circle whose radius, a c , is 12 feet? 

.0745X40X 12=8.376=length of the arc. 

2. What is the length of an arc whose chord, a b % is

And 75X8—120-*-3=160. Ans. 

Note. —The chord of half the arc is equal 
to the square root of the sum of the squares 
of the height and half the chord of the whole arc. 

II. When the chord of the arc and the chord of half 
the arc are given. 

Rule. — From the square of the chord of half the arc 
subtract the square of half the chord of the entire arc; 
the remainder will be the square of the versed sine. 
Then proceed as before. 

Note —The square root of the sum of the squares of the versed 
sine or height, and half the chord of the entire arc is equal to the 
chord of half the arc.

III. When the diameter and the ve r sed sine of half 
the arc are given. 

Rule .—From GO times the diameter subtract 27 times 
the versed sine, and reserve the number. Multiply the 
diameter by the versed sine, and the square root of 
the product will be the chord of half the arc. Multiply 
twice the chord of half the arc by 10 times the versed 
sine, divide the product by the reserved number , and 
add the quotient to twice the chord of half the arc; 
the sum will be the length of the arc, very nearly.

HODGSON’S ESTIMATOR 


Note. —The area of a circle is to the area of the circumscribed 
square as .7854 is to 1, and to that of the inscribed square as .7854 
Is to If the reader will examine the above figure, he will see 
that the square, A B C D, which is circumscribed about the circle, 
is equal to the square of the diameter of the circle, since the diam¬ 
eter,a c, equals the side A B , and A B squared gives the area of the 
square A B CD; also, that the inscribed square, abed, is just \ of 
the circumscribed square. Since each of the triangles into which 
the inscribed square is divided is precisely half of each of the four 
squares into which the circumscribed square, ABC D, is divided. 
That is, the inscribed square contains only 4 right-angled tri¬ 
angles, while the circumscribed square contains 8. Consequently, 
the square described within a circle is precisely half of the square 
described without it. 

Problem VI.—To find the area of a sector of a circle. 

Rule. — 1. Find the length of the arc by problem vii. 

2. Multiply the length of the arc thus found, by half 
the length of the radius, and the product will be the 
area. 

Or, as 300 degrees is to the number of degrees in 
the arc of the sector, so is the area of the circle to the 
area of the sector. 

Note. —If the diameter of radius is not given, add the square 
of half the chord of the arc to the square of the versed sine of half 
the arc, and divide the sum by the versed sine; the quotient will 
be the diameter. 


It is manifest that the area of the sector has the same 
ratio to the area of the circle which the number of 
degrees in the arc has to the number of degrees in the 
whole circumference; and the rule for finding the area 
of the sector, is the same as that for find¬ 
ing the area of the whole circle. 

Example. — What is the area of a sector 
of a circle, a c b , in which the radius, a c , 
is 25 and the arc of 26 degrees?

subtract the square of the less from that of the greater. 

2. Multiply the difference’of the squares by the deci¬ 
mal .7854, and the product will be the area. 

Or, multiply the product of the sum and differc7ice of 
the two diameters by .7854. 

Example. — If the diameter of 
the outer circle, a b , be 221, and 
the inner circle, d c , 106, what 
is the area of the ring? 

First, 221 2 X.7854= 38359.72 

And, 106^X.7S54= 8824.75 

Ans. 29534.97 

Note. —The area of each of these circles is equal to the square 
of the diameter multiplied by .7854 (Prob. 3). And the difference 
of these squares is equal to the product of the sum and difference 
of the diameters. Therefore, the area of the ring is equal to the 
product of the sum and difference of the two diameters, multi¬ 
plied by .7854. 

OF ELLIPSES 

Problem XI.—To find the area of an ellipse. 

Rule. —Multiply the longer axis by the shorter, and 
the product, multiplied by the decimal .7854, will be 
the area required. 

Note.— A common and more scientific name for the longei 
axis of an ellipse, is the transverse or major, and for the shorter, 
the conjugate or minor. ; 

Example. — 1. What is the area of 
an ellipse whose longer axis, a b , is 
70 feet, and whose shorter, d c, is 50 
feet? 

abxd e=7() X 50=3500. 

Then, 3500X.7854=2748.9=area. 

2. What is the area of an ellipse whose axes are 16 
and 12? 150.79. Ans,

Problem XII. —To find the circumference of an ellipse. 

Rule. —Square the two axes, and multiply the square 
root of half their sum by 3.14159; the product will be 
the circumference, nearly. 

Example. —What is the circumference of an ellipse 
whose transverse and conjugate axes are 16 and 18 
feet? 

16 2 -|-18~=580=sum of the squares of the axes. 

And, 290=half sum. 

Then, \/290X3 14159=53.498=circumference. 


Problem XIII. —To find the area of an elliptic seg¬ 
ment, cut off by a line perpendicular to either axis. 

Rule —Find the area of a corresponding circular seg¬ 
ment, having the same height and the same vertical 
axis or diameter. Then say, as the vertical axis is to 
the other axis, parallel to the segment’s base, so is the 
area of the circular segment before found, to the area 
of the elliptic segment sought. 

Exa7nple. —The height of an elliptic segment is 10, 
and the axes 25 and 35 respectively: what is the area? 

10-f-35=.2857 tabular versed sine and segment=. 18452. 

And, .18452X35 3 =249.98. 

Then, 25 : 35 : : 249.98 : 349.97=area. 


Problem XIV. —To find the area of a parabola. 

Rule .—Multiply the base by the height, and two- 
thirds of the product will be the area. 

Example .—What is the area of a para¬ 
bola, whose base, a b , is 26 inches, and 
height, d e, 18 inches? 

26X 18=468=producfc of base and height. 
468X§=312=area in square inches. 

Then 312-7-144=2^ square feet. Ans. 

Problem XV. —To find the area of a frustum of a 
parabola, cut off by a line drawn parallel to the base.

Rule .—Multiply the difference of the cubes of the two 
ends of the frustum by twice its altitude, and divide 
the product by three times the difference of their 
squares. 


Example .—What is the area of a frustum of a parab¬ 
ola whose height, c b , is 12 feet, and v

OF HYPERBOLAS 

Problem XVI.—To find the area of a hyperbola. 

Rule .—To five-sevenths of the abscissa, v e, add the 
transverse diameter; multiply the sum by the abscissa, 
and extract the square root of the product. Then, 
multiply the transverse diameter, v g y by the abscissa, 
v e , and extract the square root of that product. Then, 
to 21 times the first root, add 4 times the second root; 
multiply the sum by double the product of the conju¬ 
gate and abscissa, and divide by 75 times the trans¬ 
verse; this will give the area, nearly. 

Example .—What is the area of a Hyperbola, dfv, 
whose transverse diameter, v g, is 80, and conjugate, 
df 50, and whose abscissa, v e y is 45?

USE OF THE ABOVE TABLE 

To find the area of a segment of a circle. 

Rule. —Divide the height, or versed sine, by the 
diameter of the circle, and find the quotient in the 
column of versed sines. 

Then take out the corresponding area, in the next 
column on the right hand, and multiply it by the 
square of the diameter; this will give the area of the 
segment. 

Example. — Required the area of a segment of a cir¬ 
cle, whose height is 3^ feet, and the diameter of the 
circle 50 feet? 

31=3.25; and 3.25-^50=.065. 

.065, as per table= .021659; and .0 21659 X50 2 =54.147500, the 
area required. 

Approximating rule to find the area of a segment of a 
circle. 

Rule. —Multiply the chord of the segment by the 
versed sine, divide the product by 3, and multiply the 
remainder by 2. 

Cube the height, or versed sine, find how often twice 
the length of the chord is contained in it, and add the 
quotient to the former product; this will give the area 
of the segment, very nearly. 

Example. —Required the area of the segment of a 
circle, the chord being 12, and the versed sine 2. 

12X2=24; 24-5-3=8; and 8x2=16. 

2 3 -s-24= .3333. 

Hence 16-f-.3333=16.3333, the area of the segment, very nearly.

USE OF THE ABOVE TABLE 

To find the area of a circular zone. 

Rule i .—When the zone is less than a semicircle, 
divide the height by the longest chord, and seek the 
quotient in the column of versed sines. Take out the 
corresponding area, in the next column on the right 
hand, and multiply it by the square of the longest 
chord; the product will be the area of the zone. 

Example .—Required the area of a zone, whose long¬ 
est chord is 50, and height 15. 

15-^-50=.300; and .300, as per table=.28087. 

Hence, .28087X50 2 =702.19, the area of the zone. 

Rule 2 .—When the zone is greater than a semicircle, take 
the height on each side of the diameter of the circle, 
and find, by Rule 1 , their respective areas; the areas 
of these two portions, added together, will be the area 
of the zone. 

Example .—Required the area of a zone, the diameter 
of the circle being 50, and the height of the zone on 
each side of the line which passes through the diam¬ 
eter of the circle 20 and 15, respectively. 

20-s- 50=.400; .400, as per table=.35182; and .35182x50 2 = 
879.56. 

15-f-50=.300; .300, as per table=.28087; and .28087X50 2 = 
702.19. 

Hence, 879.56+702.19=1581.75.

To find the length of an arc of a circle by the fore¬ 
going table. 

Rule .—Divide the height by the base, and the quo¬ 
tient will be the height of an arc, of which the base is 
unity. Seek in the table for a number corresponding 
to the quotient, and take the length of that height 
from the next right-hand column. Multiply the num¬ 
ber, thus found, by the base of the arc, and the product 
will be the 1 ength of the arc or curve required.

Example .—The profiles of the intradoses of the 
arches of a bridge are each a semi-ellipse; the span of 
the middle arch is 150 feet, and the height 38 feet: 
required the length of the curve. 

38-4-150=.253, and .253, as per table=1.1628. 

Hence 1.1628x150=174.4200, the length required.

To find the length of the curve of a right semi-ellipse. 

Rule. —The rule for circular arcs in the preceding 
table is equally applicable here. 

The two last tables are not entirely confined to works 
which may be carried into practice, but are useful in 
estimating, to a very minute degree of accuracy, the 
quantity of work which is to be executed from diaw- 
ings to a scale. 

As the tables, however, do not afford the means of 
finding the lengths of the curves of elliptic arcs, which 
are less than half of the entire figure, the following 
geometrical method is given to supply the defect. 

To find the length 
of an elliptic curve, 
which is less than 
half the figure. 

Let the curve, of 

C 

which the length is 
required to be found, 
be a b c. 

Produce the versed sine, b d , to meet the center of 
the curve in e. Draw the right line, c e, and from the 
center, e, with the distance, e b } describe an arc, b h. 
Bisect c h in f, and from the center, e, with the radius, 
e i } describe the arc, i k, meeting e b produced to k; 
then, i k is half the arc ab c. 

Note *.—When the quotient is not given in the column of 
heights, divide the difference between the two nearest heights by 
.5; multiply the quotient by the excess of the height given, and 
the height in the table first above it, and add this sum to the 
tabular area of the least height. 

Thus, if the height is 118, 

.120, per table,=1.0618 
.115, “ “ =1.0567 

.0051 -i- 5 =.00102 X (118—115) = .00306, 
which, added to 1.0567=1.05976, the length for 118.

OF SOLIDS BOUNDED BY PLANE SURFACES 

The mensuration of solids is divided into two parts. 

I. The mensuration of the surfaces of solids. 

II. The mensuration of their solidities. 

The measure of any solid body is the whole capacity 
or contents of that body, when considered under the 
triple dimensions of length, breadth, and thickness. 
A cube , whose side is one inch, one foot, or one yard, 
etc., is called the measuring unit; and the contents or 
solidity of any figure is computed by the number of 
those cubes contained in that figure. 

DEFINITIONS 

1. A cube is a right prism, bounded by six equal 
square faces, of which any two, opposite to each other, 
are parallel. 

2. A parallelopipca is a prism bounded by six quadri¬ 
lateral planes, every opposite two of which are equal 
and parallel. 

3. A prism is a solid, whose ends are parallel, simi¬ 
lar, and equal, and the sides connecting these are 
parallelograms. 

4. A pyramid is a solid, whose base is any plane 
figure, and whose sides are triangles, having all their 
vertices meeting together in a point above the base, 
called the vertex of the pyramid. 

5. A frustum or trunk of a pyramid is a portion of 
the solid that remains after any part has been cut off 
parallel to the base. 

G. A wedge is a solid of five sides, two of which are 
rhomboidal, and meet in an edge, a rectangular base, 
and two triangular ends. 

7. A pris?noid is a solid, whose ends or bases are par¬ 
allel, but not similar, and whose sides are quadrilateral

OF CUBES AND PARALLELOPIPEDS 

Problem I.—To find the lateral surface of a prism. 

Rule .—Multiply the perimeter of the base into the 
altitude, and the product will be the convex, or lateral 
surface. When the entire surface of the prism is 
required, add to the convex surface the area of the 
bases. 

Example .—Required the lateral surface of a prism 
whose base is a regular hexagon, and whose 
sides are each 2 feet 3 inches, the height 
being 11 feet? 

2 ft. 3 in =27 in. and 27X6=perimeter of the base. 

11 ft. =132 inches=height. 

Then, 132x162=21384 square inches. 

21384^144=148.50 sq. ft. Ans. 

Problem II. —To find the solidity of a 
cube or right prism. 

Rule. — Multiply the area of the base by 
the perpendicular height, and the product will be 
the solid contents. 

Note.— The capacity of a vessel, in gallons or bushels, of any 
given dimensions, may be readily ascertained by calculating its 
contents in inches, and then dividing the contents by the number 
of cubic inches in. one gallon or bushel. 

Examples. —1. Required the number of 
ale gallons there are in a cistern which is 
6 feet 8 inches deep, and whose base is 
5 feet 4 inches square? 

6 ft. 8 in.=80 in. 

5 ft. 4 in.=64 in. 

Then, 64 2 =4096, and 4096X80=327680=solidity in inches. 

And 327680- 4 -282= 1162 gal.

Problem III.—To find the lateral surface of a regular 
pyramid. 

Rule. —Multiply the perimeter of the base by the 
d slant height, and half the product will be 
the surface. If the whole surface be re¬ 
quired, add to this the area of the base. 

Example. —What is the lateral surface 
of a regular triangular pyramid, a b c, 
whose slant height, d a , is 20 feet, and the 
sides of whose base are each 8 feet? 

8x3=24=perimeter of the base. 

20 =slant height. 

2 )480 

240=lateral surface. 

Problem IV.—To find the lateral surface 
of the frustum of a regular pyramid. 

Rule. —Multiply the perimeters of the two ends by 
the slant height of the frustum, and half the product 
will be the surface required. To this add the surface 
of the two ends when the entire surface is required. 

Exainple. —What is the lateral surface of 
the frustum of a regular octagonal pyra¬ 
mid, A B C D, whose slant height, a A, 
is 42 feet, and the sides of the lower base, 

D C, o feet each, and of the upper base, 
a by 3 feet each ? 

First, 5X8=40=perimeter of lower base. 

3X8=24= “ upper “ 

64=sum of the two ends, 
then, 64=42-5-2= 1344=area of lateral surface.

Problem V. —To find the solidity of a pyramid. 

Rule— Find the area of the base, and multiply that 
area by J of the height. 

Note. —This rule follows from that of the 
prism, because any pyramid is £ of a prism of 
the same base and altitude. It is manifest, there¬ 
fore, that the solidity of a pyramid, whether 
right or oblique, is equal to the product of the 
area of the base into § of the perpendicular 
height. 

Example. —What is the solidity of a 
square pyramid, abed , the sides of 
whose base are each 30 feet, and its per¬ 
pendicular height, ef 25 feet? 

First, 30X30=900=area of the base. 

25-3= 

7200 
300 

7500=solidity. 

Problem VI. —To find the solidity of the frustum -of 
a pyramid. 

Ride. —To the areas of the two ends of the frustum, 
add the square root of their product; and this sum, 
multiplied by J of the perpendicular 
height, will give the solid contents. 

Note. —This rule holds equally true to a pyra¬ 
mid of any form. For the solidities of pyramids 
are equal when they have equal heights and bases, 
whatever be the figure of their bases. 

Example. —What is the cubic or solid 
contents of the frustum of a marble pyra¬ 
mid, whose lower base, abed , is 20 
inches square, and upper base, e f 14 
inches, and whose height,/^, is 8 feet 4 inches? And 
what will be its weight, reckoning 109 lbs. to the cubic 
foot?

OF THE CYLINDER, CONE, AND SPHERE 
DEFINITIONS 

1. A cylinder is a solid, having equal and parallel 
circles for its ends, and is described by the revolution 
of a rectangle about one of its sides. 

2. A cone is a solid body, of a true taper from the 
base to a point, which is called the vertex, and has a 
circle for its base. 

3. A frustum of a cone is what remains after a por¬ 
tion is cut off by a plane, parallel to the base. 

4. A conoid is a solid, generated by the revolving of 
a parabola or hyperbola around its axes. 

5. A spheroid is a solid, generated by the revolution 
of an ellipse about either of its axes. 

6. A sphere is a solid, terminated by a curved sur¬ 
face, all the points’of which are equally distant from 
a point within, called the center. A sphere may be 
described by the revolution of a semicircle about a 
diameter. 













72 


HODGSON’S ESTIMATOR 


7. A radius of a sphere is a line drawn from the 
center to any part of the surface; as, 

8. The diameter of a sphere is a line drawn through 
the center, and terminated at both ends by the surface. 
All diameters of a sphere are equal to each other, and 
each is double the radius. 

9. A segment of a sphere is a portion of the sphere 
cut off by any plane. This plane is called the base of 
the segment. The height of a segment is the distance 
from the middle of its base to the convex surface. 

10. A zone is a portion of the surface of a sphere, 
included between two parallel planes, which form its 
bases. If the bases are equally distant from the cen¬ 
ter, it is called the middle zone. The height of a zone is 
the perpendicular distance between the two planes 
which form its bases. 

11. A cylindrical ring is a solid, formed by bending a 
cylinder, as a cylindrical bar of iron, until the two 
ends meet each other. 

12. A parabola is a section of a cone when cut by a 
plane parallel to its sides. 

13. A hyperbola is the section of a cone when cut by 
a plane, making a greater angle with the base than the 
side of a cone makes. 

14. The transverse axis is the longest straight line 
that can be drawn in an ellipse. 

15. The conjugate axis is a line drawn through the 
center, at right angles to the transverse axis. 

1G. An abscissa is a part of any diameter contained 
between its vertex and an ordinate. 

17. The focus is the point in’the axis where the 
ordinate is equal to half the perimeter. 

Problem I.—To find the convex surface of a cylinder. 

Rule. —Multiply the circumference of <he base by the 


AND CONTRACTOR’S GUIDE 

length of the cylinder, and the product will 
be the convex surface required. To this add 
the areas of the two ends when the entire sur¬ 
face is required. 

Example .—What is the convex surface of a 
right cylinder, whose length is 23 feet, and the 
diameter of its base 3 feet? 

3X3.14159—9.42477 
Then, 9.42477x23=216.76971=surface 

Problem II.—To find the solidity of a cylinder. 

Rule .—Multiply the area of the base by the height, 
and the product will give the solid contents. 

Examples. —1. What is the solidity of a 
cylinder, the diameter, a 1 ?, of whose base 
is 16 feet, and its height, ef 28 feet? 

First, find the area of the base by 16 J =256. 
Then, 256X .7854= 201.0624=area of the base. 
Then, 201.0624 X 28=5629.7472=solid contents. 

2. The Winchester bushel is a hollow 
cylinder, 18J inches in diameter and 8 
inches deep: what is its capacity? 

First, the area of the base= 18.5'X .7854=268.8025. 

Then, 268.8025x8=2150.42—capacity in cubic inches. 

Note. —By this rule, every sealer of weights and measures may 
determine the exact capacity of any measure submitted to his 
inspection. And so any one may test the accuracy of any 
measure, whether dry or liquid, by reducing its capacity to cubic 
inches, and dividing by the number of cubic inches contained in 
such measure. The divisor for any measure may be found in the 
Table of Weights and Measures. 

3. How many gallons of oil will a can of a cylin¬ 
drical form hold, whose diameter is 28J inches, and 
whose height is 4 feet 3 inches?

Problem III.—To find the convex surface of a :one. 

Rule. —Multiply the perimeter of the base by the 
slant height, and \ the product will be the surface; to 
which add the area of the base when the entire surface 
is required. 

Example. —The diameter of the base of a right cone, 
a b y is 3 feet, and the slant height, c a , is 15 feet: what 
is the convex surface? 

First, 3X3.14159=9.42477=circum. of base. 

Then, 9.42477X 15^2=70.686 sq. ft. 

Problem IV.—To find the solidity of a cone. 

Rule. —Multiply the area of the base by J of the 
height, and the product will be the solidity. 

Example. —What is the solidity of a right 
cone, whose perpendicular height, c d , is 
10£ feet, and the circumference of the base 
is 9 feet? 

We here multiply the area of the base 
by J of the height, and the product is the 
solidity. 

First, 9 2 =81, and 10^3=31=1 height. 

Now, 8lX .7854=63.6174, area of base. 

Then, 63.6174x31=222.6609. Ans. 

Problem V.—To find the surface of a frustum of a 
cone. 

Rule— Add together the circumferences of the two 
ends, and multiply the sum by J the slant of the frus¬ 
tum; the product will be the convex surface: to which 
add the areas of the two bases when the entire surface 
is required. 




AND CONTRACTOR’S GUIDE 


75 


Note. —This rule is precisely the same as that for a frustum of 
a pyramid, and if a cone be considered as a pyramid of an infinite 
number of sides, it is equally applicable to the measurement of 
the frustum of a cone. 


Example .—What is the convex surface of the frus¬ 
tum of a cone, the circumference of the greater base, 
a b , being 30 feet, and of the smaller, e f, 10 feet, the 
slant height, c a, being 20 feet? 

30+10=40=circum. of two ends. 10=i slant height. 

40x 10=400=convex surface. 

Problem VI.—To find the solidity of the frustum of a 
cone. 

Rule .—Add to the areas of the two ends of the frus¬ 
tum the square root of their product. Then multiply 
this sum by J of the perpendicular height, and the 
product will be the solidity. 


Note.—I f a cone and a pyramid have equal bases and altitudes, 
they are equal in their solidity. Consequently, the rule already 
given for the frustum of a pyramid is equally applicable to the 
frustum of a cone. 


Example .—Flow many gallons of ale are 
contained in a cistern in the form of a conic 
frustum, a b e f if the larger diameter, a b y 
be 9 feet, and the smaller diameter, e f 7 
feet, and the depth, cod, 9 feet?

Problem VIII.—To find the convex surface of a 
spherical zone or segment. 

Rule. —Multiply the height of the zone or segment

Exaynple. —If the axis of a sphere be 42 inches, what 
is the convex surface of a segment or zone, a b d, 
whose height, c d, is 9 inches? 

First, 42x 3.14159=131.9468=circumference

1187.521 2=surface in square inches. 

Problem IX.—To find the solidity of a sphere or 
globe. 

Rule. —Multiply the cube of the diameter, c e, by the 
decimal .5236. Or, multiply the square of the diam¬ 
eter by the circumference, and J of the product will be 
the contents. 

Example. —What is the solidity of a globe whose 
diameter, c e, is 12 inches? 

12"x3.14159=452.38996=surface of the sphere. 

Then, 452.38996X 12-r-6=904.78=solidity.

frequently required when the radius of its base 
is not given; but if the diameter of the sphere 
and the height of the segment be known, 
be easily found by the following:

GAUGING OF CASKS 

Gauging is a practical art which does not admit of 
being treated in a very scientific manner. 

Casks are not commonly constructed in exact con¬

To find the contents of a cask by four dimensions.

We are now in a position to commence work in 
earnest, and with this end in view we will start just as 
the workman starts, at the very beginning, which, in 
the case of a building, is the preparation of the site, 
the excavations, the drainage, the footings, the foun¬ 
dations, and so on, until the whole structure is finished; 
and I would like to remark before commencing that 
whatever method of estimating is started with, that 
method should be continued throughout the whole for 
that particular work. Sometimes, where there is any 
doubt as to the correctness of the result, it is a good 
way to finish up with one system, then to use another 
system, and if the two results are not wide apart, the 
estimate may be considered fairly correct. If, how¬ 
ever, there is a big variation, the first estimate should 
again begone over, and if the same result is obtained, 
or nearly the same, it maybe considered fairly correct; 
it is well, however, to go over the second system again 
in order to find out where the discrepancy occurs. 
The price of accurate results is persistent effort. 

In order to get at near approximation of the cost of 
work, the estimator, besides having a knowledge of 
the price of the various materials required, should 
be also conversant with the current price of labor, and 
to this end I give herewith the average price per hour 
af labor as now (1904) gathered from a number of labor

circles throughout the whole country. These prices, 
however, are only given merely as guides, for they 
will vary with time and with locality; but in the 
absence of proper local data, they may be used with 
confidence. I give the price per hour of labor, as law 
or custom has not yet made the length of a legal day’s 
labor.

CONCRETE WORK 

Concrete should be composed of pure clean water, 
broken stones, or ballast or clean p’t-gravel, with such 
a proportion of sharp sand as will fill the voids 
between the stones or gravel; and this latter should 
not be larger than such as will pass through a ring 1 
inches in diameter. The proportion should never be

less for Portland cement than one to six parts of stones 
and sand combined, and the concrete should be 
thrown into position steadily and as evenly as possible 
and tamped down in layers not more than twelve inches 
thick. The following prices include mixing, wheel¬ 
ing, throwing in place and tamping down. Of course 
something will depend on the cost of cement, and on 
the cost of aggregate, i.e., broken stone and sand.

CONCRETE FLOORS AND ROOFS

AND CONTRACTOR S GUIDE 89 

Portland cement, four parts of broken bricks, slag or 
other porous aggregate, and should be small enough to 
pass through a f-inch ring; but no sand should be used. 
Fine ashes from the smith's forge make the best 
material for this purpose, but it should not exceed in 
bulk one-third of the whole mass. The concrete 
should be laid in position gradually and continuously, 
until the whole work is done, and should be tamped 
concurrently as laid in place. Concrete under boarded 
floors, tile or brick pavements should be as above 
described, but in the proportion of one part Portland 
cement to five parts of aggregate, which, after being 
thrown in place, should be leveled off nicely and 
tamped down with a wooden pounder until it becomes 
pulpy and the “fat" or cement portion is brought to 
the surface, when it should be floated or finished to a 
fine smooth face with a wooden float.

EXCAVATING FOR TRENCHES, DRAINAGE, 

FOOTINGS AND SIMILAR WORK 

0 

As before stated, the prices given in this work are 
not to be considered good for all time. The prices 
given to-day will be found quite unreliable in a month 
or two, or when applied to another locality. The 
prices, however, I do affix to the work specified may 
be considered moderate and fairly safe for competitive 
tendering, but it is always best to vary these prices by 
local quotations and current rates. 

I have already given a few instructions to the intend¬ 
ing contractor with reference to excavating, but it may 
be well, even though I may lay myself open to the 
crime of repeating myself, to reiterate in some measure 
those instructions and warnings. 

The plans of the intended specifications should be 
well studied and specifications carefully read over, so 
as to thoroughly understand what the architect 
desires, and when things are not properly digested the 
architect should be consulted. 

The site of the intended building should be visited, 
so that the nature of the soil may be known, the dis¬ 
tance it is to be conveyed, the state of the roadway, 
and the distance the building materials have to be 
hauled. See to the levels, and ascertain as nearly as 
possible the amount of material to be removed. Some¬ 
times, in digging, a very different soil reveals itself to 
that taken; there are sometimes loose sand, running 



AND CONTRACTOR’S GUIDE 


9 1 


water, rock, and other obstacles that have not been 
considered, and the price per yard for digging, removal 
of loose material, strutting sides of trenches, pumping, 
and cost of carting may make a considerable differ¬ 
ence. The builder who knows the locality or site and 
the sub-soil is, of course, in a better position than 
others who tender. On some sites sand may be found 
a few feet from the surface, and this may be valuable 
and make a difference to the price; or it may be the 
sand has been screened and placed again on the site 
and covered with loam, in which case the excavations 
will have to go down to the “virgin” soil. 

The cost of materials should be obtained before 
estimating. The prices of stone, bricks, sand, lime, 
ballast, delivered on the site, are all-important pre¬ 
liminaries to correct estimating. The prices of bricks, 
sand, lime, etc., vary very much in different localities. 
To take brick work, several elements are necessary 
before a correct price can be affixed per rod; as, for 
example, the price of bricks in field, the carriage to 
works, if by barge or rail, the cost of loading, the 
freight, unloading, carting from wharf to works, the 
price per yard of sand delivered, and of lime, and 
cost of labor. If there are any terra cotta or drain 
pipes, the cost delivered on the site should be obtained 
from the maker, and the same for any iron work or 
other special material. 

As all these elements are found to vary considerably, 
it is only possible to obtain an approximate price. 
The market prices of leading items in each trade ought 
to be known, and for this purpose trade lists and prices 
are necessary. The quotation of prices for particular 
items is important. 

More uncertainty prevails in estimating excavator’s 


92 


HODGSON’S ESTIMATOR 


work than in any other of the builder’s trades, owing 
to the various kinds of soil to be removed, if the soil is 
earted or wheeled a long or short way, if the excava¬ 
tion is deeper than G feet (the height a man can work), 
if filled in, where deposited. This item is taken 
according to the labor involved. It may consist sim¬ 
ply of digging and carting, as in the excavation over 
the site, or of digging, filling, and ramming, as in 
trenches for foundation. In the latter, however, both 
kinds of labor are required. Thus, the “digging and 
carting’’ represents that portion of the excavation 
which is occupied by the wall and has to be removed, 
and the “filling and ramming’’ applies to that portion 
of earth which is filled in and rammed against the 
walls. Then it is necessary to keep such items sep¬ 
arate, as, for example, the excavation to basements 
and those only on the surface, as in removing the top 
soil and wheeling away not exceeding say 9 or 12 
inches deep. In the deeper excavations in friable soils 
timbering is necessary, as walling and strutting the 
sides of trenches, etc. 

In pricing items of excavation, the depth and width 
of trench, the nature of the soil, and the quantity of 
timber, if necessary, the latter measured per foot 
super, on each side, must be known. Digging in 
gravel or stiff clay costs twice as much as in loose 
earth. The disposal of the stuff should be made clear. 
Thus, the part of the trench to receive concrete may 
be described as “excavation and carting away, or 
wheeling and spreading,” the portion to receive the 
brick work being described as “digging to trenches, 
part filled in and rammed, and remainder carted away.” 
The earth may be dug and thrown out, wheeled or 
basketed out, or carted away to make up other ground. 


AND CONTRACTOR’S GUIDE 


93 

Depths of 6 feet, 12 feet, or 18 feet should be kept 
•eparate. 

Wall trenches in width are regulated by the spread 
of the footings, usually twice the thickness of wall at 
base, and room enough for men to work in the trench 
on one or both sides, usually (3 inches beyond bottom 
course of footings. 

Pumping and bailing out water is a speculative item, 
and its cost can only be approximately put down. 

I have shown in previous pages approximately the 
cost of handling loam, sand, gravel and general rub¬ 
bish, and the prices given these hold good in nearly 
all cases, but exceptional conditions must be provided 
for, 

For large trenches and foundation work, when the 
earth is filled in and rammed, it is perhaps better to 
make a separate item, as “excavation and returning, 
filling and ramming,” the quantity measured from 
outer face of brick work to side of trench by the depth 
of the footings, and deduct this from total excavation. 

Priced bills do not help the young estimator much. 
To take two or three priced bills of quantities for the 
same building will reveal extraordinary differences, 
arising from various circumstances—the position and 
facilities of the contractor, his nearness to the work, 
whether he has a large plant and staff of workmen, or 
is a man of small capital without resources; the prices 
also depend on whether the estimate is prepared with 
the aid of drawings or specifications, or simply from a 
bill of quantities, from the items of a day or measured 
account. A man may be an expert quantity taker who 
has not mastered the fundamental elements of pricing: 
the two processes are different. The expert in prices 
must be a man naturally addicted to study and com- 


94 


HODGSON’S ESTIMATOR 


pare values, to analyze the composition of items; he 
must be able to arrive at a price by a calculation in 
detail. A mind so trained will be able to trace analo¬ 
gous conditions, will be able to generalize and com¬ 
pare. We should recommend the young estimator to 
master the contents of every trade l : st of materials and 
goods, and these should be kept, classified and 
indexed, on some system for easy reference. The 
trade and cash discounts, railway rates, cost prices, 
etc., should be collected and indexed for reference, 
and for this purpose an alphabetical index or common¬ 
place book ought to be kept. A book for each trade 
should be kept to enter prices, data, and information, 
always giving date. Note especially the time expended 
on every kind of labor, as, for example, the time takei 
by a laborer in digging a yard cube of clay or othe 
material, how many yards he can do in a day; thv 
time it will take a joiner to frame a door of a certair 
thickness per foot super., or the time it takes to d< 
any unit of work. 

Large quantities of material, like sand or ballast o: 
bricks, can be procured at a cheaper rate than smah 
supplies, and a difference of at least 10 per cent in the 
cost may be made; but in every particuar instance it is 
better to make inquiries and obtain quotations from 
reputable dealers and contractors. 

The presence of sand on the site will often save 
much carting away, as the sand and ballast can be used 
for concrete and brick work, and before pricing items 
of excavation inquiries should be made as to the depth 
of the sand below the ground level All above the 
sand has to be carted away; it may be half or two- 
thirds of the whole depth excavated. When sand 
occurs in the trenches and site considerable saving is 


AND CONTRACTOR’S GUIDE 


95 


effected, and the exact quantity of this should be 
ascertained before pricing, so that an allowance can be 
made. Thus, in trenches say half full of good sand, 
one-half only of the quantity or of every yard would 
have to be carted away. The other portion will be a 
distinct gain. The sand should be valued at so.much 
per yard cube, added to the saving ot carting, so that 
there should be a great saving. It is better to provide 
that a certain sum shall be allowed by the contractor 
for every yard of sand found on site and used in the 
building.

shows a trench, 3 feet 6 
inches deep and 3 feet wide, 
that is prevented from cav¬ 
ing in by the use of cross 
struts and planks placed at a 
distance of about G feet.

be dug in good solid ground. 
These struts and planking 
will require about 10 feet of 
material for every 6 feet in 
length of the trench, and

very strong. This is an expensive affair; but the 
materials for use in the framework, when carefully 
removed, may be used again for the same or similar 
purposes. This style would cost about SI.50 per run¬ 
ning foot, exclusive of digging and removing material.

somewhat on the depth of 
cutting. Supposing this to 
be about 0 feet deep, the 
cost would be from 75 to 85 
cents per running foot, which 
would, of course, include 
both sides and cost of plank¬ 
ing and poles. Some allowance would have to be 
made for the return stuff, as most of the material could 
be used again for a similar purpose. The prices given 
do not include digging or removing the loose earth, 
but simply the shoving and the material used; but 
these prices will vary with the locality and cost of 
material and labor.

or loose ground. This is an expensive necessity wher¬ 
ever it has to be undertaken, and requires two stories, 
as it were, of shoring and an extra widening of the 
trench at the top. The sheet piling is of plank two or 
three inches thick, as may be required, and each plank 
is pointed at one end and is driven into the soil at the 
bottom of the wide trench as shown, and is strutted 
and made secure, after which the lower trench is exca¬ 
vated and secured with piling and struts as shown. 
This style of planking and securing the work is very 
expensive, and each case must be figured out for 
itself; the cost depending largely on depth and width 
of trench and quality of earth to be supported. I have 
known of such work as described costing $6.50 per 
running foot for labor and materials for the purpose; 
the trench being about 14 feet deep on an average. 
This was exclusive of digging and removing the earth 
from the trench. Under the circumstances, it would 
be folly to give any stated price for this work. An 
approximate cost can only be obtained by actual figur¬ 
ing on the particular work to be done, and it is always 
the surest way, in cases like the one under notice, to 
make no allowance for returned material, for, when 
taken out of the trench, it will have but little value for 
any other purpose.

Ordinary earth.2 ft. to 3 ft. 

Dry sand or gravel ..1 ft. to 2 ft. 


In trimming banks fora permanent surface the slope 
should not be uniform, but flatter at the lower than 
the upper part. For instance, in the same soil (clay), 
a bank 5 feet high may stand at a slope of 1£ to 1; 
10 feet high, 2 to 1; 20 feet high, 3 to 1, with prac¬ 
tically the same permanency. The most economical 
section for a deep cutting or hillside would be a slope 
ranging from 3 to 1 at bottom to to 1 at the top.

A usual allowance for settlement is one inch for

A good excavator will dig and throw into a barrow 


in a day of ten hours: 

In common ground.from 8 to 10 cub. yd. 

In stiff clay or firm gravel. “ 5 to 6 “ 

In hard ground (picking required). “ 3 to 5 “ 


In excavating, a vertical throw is taken at 0 feet, and 
when a trench exceeds that depth, stages must be pro-

IOI 


vided. In practice, stages are usually set at somewhat 
closer intervals. 

Clay invariably swells on exposure of the face in an 
excavation, and allowance must be made for this in 
certain works, as in well-digging and tunneling. 

In calculating the quantity of excavation in a trench 
which tapers in depth or width, the prismoidal formula 
should be used, viz., area of two ends plus four times 
middle area, and the total multiplied by one-sixth of 
the length. 

For an irregular site take spot levels, join all up into 
triangles, then multiply the mean depth of each tri¬ 
angle by its area. 

A run is a certain distance for wheeling excavated 
material. With a length of one run, two barrows can 
be kept going without waiting. The length of a run is 
commonly taken to be 20 yards, but according to some 
it is only 18 yards, while in some districts 22 yards 
is allowed, and in U. S. government work 25 yards 
make one run. If wheeled more than three runs, a 
higher proportionate price has to be paid.

A wheelbarrow contains yard cube. 

A small earth wagon will hold 1 h cubic yards. 

A large earth wagon will hold 3 cubic yards. 

1 yard cube of solid earth or gravel contains 27 striked bushels 

before digging, and 27 heaped bushels when dug 
49 square yards = 1 rood of surface digging in country. 

I have shown some of these tables in different forms 
in order to meet the several local customs of dealing 
with the same conditions; a method which, I think, 
will give this little work wider range than it would 
otherwise have. 

I now offer some short rules on excavating that may 
sometimes be found handy: 

A 10-ton locomotive steam crane excavator, fitted 
with a H-yard cube digging bucket, will excavate and 
deliver into wagons from 800 to 1,000 cubic yards per 
day of 10 working hours according to the nature of 
the ground. 

Work in trenches costs 20 to 30 per cent more than 
digging over areas where the labor is not cramped. 
The soil is merely deposited at a safe distance (of say 

2 feet) from the edge of the trench, from whence it is 
wheeled or carted away. Take common ground, a 
man would here be able to manage only 8 yards cube 
in one day, as there is a limited space to work in and 
the soil has to be pitched out one “throw.” Earth 
that is loose enough to shovel out without using the 
pick, and where only one “throw” is required, may be 
removed for about 12 cents per yard cubic, or for less, 
where a plow and scraper can be employed. With the 
aid of plow and scraper, earth may be removed any¬ 
where less than 100 yards for about 16 cents per cubic 
yard. If loaded in carts or wagons, it will cost from 20 
to 30 cents per yard. Very hard clay, gravel or hard-

pan may cost from 50 cents to $1.25 a yard to remove. 
Rock will cost from $1.25 to $6.00 to remove, depend¬ 
ing on the kind of rock. Old foundations, when stone, 
brick, old timber and lath, etc., are buried in mortar 
and other debris, will cost from 75 cents to $4.00 to 
remove a cubic yard from the ground to a distance not 
exceeding 100 yards. This includes digging, loading, 
chopping and unloading.

merits to make a tolerably fair estimate of the cost of 
any excavations that he may be called upon to figure 
up. As I have before stated, the thing in estimating 
to insure fairly correct results is “sound judgment’’ 
added to experience. The rules and methods, pub¬ 
lished in this and other work, on estimating are simply 
the tools with which the estimator works. If he be a 
good workman, a man of judgment, he will make a 
good job; if not, no matter how good the tools may 
be, the work will show up bad, and the contractor will 
feel himself poorer when the work is finished than 
before he started. 

LAYING DRAIN PIPES, WEEPING TILES, ETC. 

The size of drains are determined by the quantity of 
sewage to be conveyed and the velocity of the sewage 
flow. No house drain should, however, be less than 
4 inches in diameter. They should be laid in perfectly 
straight lines with an even gradient from point to 
point, the necessary junctions or changes of direction 
being within convenient inspection chambers or man¬ 
holes. 

The velocity of the flow of sewage in ordinary house 
soil drains should be about 4£ feet per second (270 feet 
per minute) when flowing full, so that they may be 
self-cleansing when only a normal quantity of sewage 
is passing through them. 

The quantity of sewage and waste water to be 
removed from dwellings, for all purposes, varies from 
25 to 40 gallons per person per 24 hours. The drains 
should be large enough to remove one-half the esti¬ 
mated total daily volume of sewage within six hours. 

Rainfall .—The provision for rainfall should be varied 
according to the district, the average annual rainfall for 


AND CONTRACTOR’S GUIDE 


105 


which can be ascertained. Rain-water drains must be 
sufficiently large to conveniently remove the whole of 
the water which may be expected to fall during the 
prevalence of a heavy storm. 

The average rainfall from roofs in this country may 
be taken at 16 inches per annum, after allowing for 
loss by evaporation, absorption, etc. 

Provision should be made for removing rainfall per 
hour as follows: 


From roofs (measured horizontally).75 inches in depth. 

From paved surfaces.75 “ 

From gravel surfaced.4 “ 

From meadows or grass plots.1 “ 


For ordinary houses, drains having 4-inch branches 
and 6-inch mains are generally sufficient. Villas and 
large houses usually require larger mains, but pipes of 
the smallest size which may be considered adequate 
should be used, as being more self-cleansing than 
larger pipes. 

An easy rule to remember for the purpose of deter¬ 
mining the gradients of drains so as to secure good, 
self-cleansing velocities for the sewage, is the follow¬ 
ing well-known “decimal rule.” Multiply the diam¬ 
eter of the pipe by 10, and the result gives the gradient 
for the drain, viz.:

Flushing .—Where self-cleansing falls cannot be 
obtained for the drains, periodical and, preferably, 
automatic flushing should be resorted to. 

Rain-water drains .—Where drains are solely used for 
rain-water, much less fall is required than for sewage. 
Generally, a velocity of 2^ to 3 feet per second (150 to 
180 feet per minute) is sufficient in order that the ordi¬ 
nary dust and dirt may be readily washed away; but 
the amount of water to be removed in a given time 
must be allowed for. The drains should be surrounded 
in concrete when passing through buildings or near the 
roots of trees, or wherever they are likely to be 
disturbed. 

Drains should be kept as far away as possible from 
buildings, so that the pipes and joints may not be 
injured or disturbed by any settlement of the walls. 
By this means the risk of sewage or sewer air pene¬ 
trating within the buildings is minimized. For similar 




















AND CONTRACTOR’S GUIDE 


wy 


reasons the drains should not pass under houses except 
when absolutely unavoidable, and in such circum¬ 
stances heavy cast iron pipes with caulked lead joints 
should be used. 

An unyielding bed on which to lay the drains is 
necessary to ensure sound and permanent work. A 
layer of concrete should therefore be provided under 
the pipes, unless the ground is naturally very hard and 
compact. 

Branch drains should not join the main or collecting 
drains with level inverts. The junction should be 
effected within an inspection chamber or manhole, 
and the branch channels arranged to discharge over 
the channel of the main drain. Care should be taken 
that the branch channels are placed so that they do 
not discharge immediately opposite each other when 
entering the main, channel. 

Stable drainage should be kept separate from the 
house drainage in all cases where practicable. 

Covers to inspection chambers should have a clear 
opening of 24 by 18 inches, so that a man may con¬ 
veniently pass through them. 

The materials of which drain-pipes are made varies 
considerably in different localities. Well-burnt stone¬ 
ware pipes of good quality are thoroughly vitrified, 
and when broken present a fine close grain with a 
somewhat metallic appearance. Fire-clay pipes do not 
possess such a dense and close grain, and are more 
absorbent than stoneware pipes. Earthenware pipes 
are quite unsuited for use in house drainage. 

Stoneware drain-pipes should be of the description 
known as “salt-glazed,” so as to obtain an impervious 
and lasting surface. For ordinary house drainage pur¬ 
poses the pipes are usually made in 2-foot lengths. 


108 


HODGSON’S ESTIMATOR 


Specially selected and tested stoneware pipes in 
3-foot lengths may be obtained from manufacturers at 
a slight additional cost over ordinary pipes. “Tested” 
pipes should be capable of withstanding a pressure of 
25 feet head of water without showing signs of sweating. 

Neat Portland cement is generally used for jointing 
ordinary spigot and socket pipes, or cement and sand 
in the proportions of one part cement to one part 
sand. 

Cement joints must be very carefully formed and 
wiped out as the work proceeds, so as to avoid burrs 
on the inside of pipes. 

Greater security is obtained by adopting one of the 
several well-known forms of patent safety joints now 
made by the leading manufacturers. They are more 
expensive than pipes with ordinary spigot and socket 
joints, but the advantage of obtaining a stronger and 
safer connection more than counterbalances the addi¬ 
tional cost. 

Protection against fracture can best be obtained by 
entirely surrounding the pipes with concrete. A thick¬ 
ness of G inches of concrete is usually sufficient for this 
purpose. 

The average thickness and weight of glazed stone¬ 
ware drain-pipes per 2-foot length is as follows, viz.:

The cost per foot of these pipes should be obtained 












AND CONTRACTOR’S GUIDE 


109 


from the dealer, along with the extra cost of Wys, 
V’s or other connections that may be required, before 
any estimate is made. If the drain-pipes are to be laid 
in concrete, the cost of the concrete and labor of put¬ 
ting it in place must also be added. The digging of 
trenches has been dealt with before, but in making an 
estimate this item of digging and removing the soil 
must not be overlooked. It is not possible to give a 
price for work of this kind unless the size of pipes, 
depth of trench, if or if not bedded in cement or con¬ 
crete, etc., are given; then a price per foot in length 
may be arrived at. 

Cast iron pipes are largely used in high-class drain¬ 
age work. The cost is not much more than that of 
good glazed stoneware surrounded with 6 inches of 
concrete. 

The advantages obtained by the use of cast iron 
pipes as compared with glazed stoneware are as follows: 

1. The pipes are of greater strength. They are 
consequently not so liable to become fractured or 
broken. 

2. Air and water-tight joints can be readily made by 
running with molten lead and caulking. 

3. Fewer joints are required, owing to the longer 
lengths of the pipe. 

For substantial work the iron pipes should be of 
similar thickness and strength as those used for ordi¬ 
nary water mains. They are generally laid in 9-foot 
lengths, with spigot and socket joints run with lead 
and caulked. 

Whenever a drain passes under or through a wall it 
should be of iron, then if any settlement takes place 
the iron will offer a much greater resistance to the 
consequent pressure than glazed earthen tiles would.

Weeping tiles may be common field tiles, or they 
may be ordinary drain tiles of small diameter. They are 
made use of occasionally to drain around a foundation 
wall, or to drain under the concrete floors of a cellar. 

When field tiles are employed they butt at the joints, 
which are not made tight, as water is intended to enter 
the pipes at every joint. The same, also, with ordi¬ 
nary tiles, the joints being left loose so that water may 
enter at every joint. 

The cost of laying weeping tiles is very small, as a 
man will lay 30 or 40 feet per hour, but the cost of the 
tile themselves must be considered. There will be no 
excavating for these tiles, as, in the case of a cellar, 
the tiles are laid on about the same level as the foun¬ 
dation; the tiles are laid on a level, and against the 
footings. Of course, the tiles in both cases must lead 
into the main drain, and this may necessitate some 
extra digging. 

FOUNDATION FOOTINGS 

In placing footings a special rate should be made, as 
much more care and time is required in getting good 
flat stones of the proper thickness, and leveling them 
on their beds, than in laying an ordinary wall. In 
my own practice I have usually charged up 50 per 
cent more per cord for footings than for the other por¬ 
tion of stone wall, and this additional charge has been 
found not a bit too much in most cases. If the foot¬ 
ings are of concrete, as is generally the case now, then 
this must be charged in accordance with the rules 
given under the head of concrete. Concrete footings 
may be flat or they may have a broad base and narrow 
top, just wide enough to take the walls, whether of 
brick or stone.

fully 5 feet 6 inches across. In estimating for this, the 
concrete must be figured at so much per cubic yard, and 
full allowance made for wheeling and dumping. The 
brick or stone work above, until the level of the 
ground is reached, should be charged up about 10 per 
cent above the regular rates. 

If footings are laid in with ordinary quarried stones

without dressing, the cost will be about $5.00 a cord of 
100 cubic feet, exclusive of all materials. Cost of 
materials, stone and mortar, to be added, and if laid 
in cement the cost will be a trifle more. 

Ordinary quarried stone laid in the wall, set in good 
lime mortar, is worth at the present time $6.50 per cord 
of 100 feet in the wall for setting. 

In buying rough quarried stones by the cord, which 
is the usual way in most of the states and Canada, the 
purchaser is supposed to receive 128 feet cubic in the 
rough, but the mason’s measurement, including mortar 
joints, is 100 cubic feet in the wall for one cord; and 
when he buys he expects to pay for the 100 feet per 
cord and to receive pay on the same basis. 

In putting in stone foundations as above, the esti¬ 
mator must make provision for all openings, and when 
cut stone or cement sills and lintels are used for doors 
or windows, they must be charged up extra by the run¬ 
ning foot. All ventilators must be extra items and 
duly charged. Figure for all openings for drain¬ 
pipes, water, gas, or other pipes entering the basement 
or cellar. All areas must be figured on by the yard 
super., if in cement or stone, according to prices 
given; steps, walls and copings must all be measured 
off and charged up according to size and material. 
Prices, if not found in this work, must be ascertained in 
the locality where the work is to be executed. 

Sills and lintels, in either stone or cement, may be 
bought from the dealer by the foot super, or cubic 
foot, and price lists of same may be obtained from the 
manufacturers. 

Footings and basement or cellar walls are some¬ 
times specified to be made damp-proof, and the archi¬ 
tect sometimes shows how the walls are to be con- 


AND CONTRACTOR’S GUIDE

structed so as to be damp-proof. I show two methods, 
both of which are expensive but certain in result. Fig. 
0 shows a concrete 
footing with a section 
of concrete carried 
up the walls to the PAnp-pxoor 
height of top of cellar 
floor, which is also of 
concrete 4 or 6 inches 
thick. A damp-proof 
course of slate or as¬ 
phalt is shown on a 
line with cellar floor, 
and is continued on the outside wall to a point above 
the line of ground. This is an effective method. In 
this case the concrete is worth from 10 to 15 per cent 

more to put in place than if 
a simple footing as above. 
Damp-proof course is 
worth from 15 to 25 cents 
a running foot, according 
to the thickness of the 
wall. 

The footing shown at 
Fig. 10 is a still more ex¬ 
pensive one. Here is a 
wide footing in concrete 
and a double wall for a 
portion of the height. 
There is a damp course of 
slate laid at L in the main 
wall and level with the finishing coat of cement, M, on 
the cellar floor. The outside wall, R, is simply to hold 
back the soil on the outside, thus forming a 12-inch 



Fig. 10 






























































HODGSON’S ESTIMATOR 


1 14 

space between the walls for air and to avoid damp. 
Concrete is thrown in between the walls below to a 
thickness of 8 or 10 inches, thus preventing any damp 
from attacking the main wall. The space between the 
two walls is covered over at the top with a stone slab, 
J, which prevents any rain or other water from gaining 
entrance. 

Here we have several new items to figure on. Extra 
bricks in outside wall, covering slab, concrete in air 
space and damp course. Figure the concrete by the 
yard cubic, the slab by the running foot, the extra 
bricks in the usual manner and the damp course same 
as before mentioned. 

We are now in a position to describe some of the 
methods of estimating as mentioned in previous pages, 
and will endeavor to do so before entering into detail 
estimating. 

As I have stated before, there are five* distinct 
methods of estimating, namely, by rough quantities, 
by the square, by the unit of accommodation, by 
cubing, and by itemizing details. The two latter may 
be considered the best methods of the five, and the 
last the best of all, though the most troublesome. Of 
the first three I will say but little, as they will be apt 
to lead the ordinary contractor into a maze of diffi¬ 
culties that will eventuate in loss of time and money; 
besides, a fairly correct description of them and the 
method of using them have been already presented. It 
may be well, however, to make a few remarks con¬ 
cerning them. 

The cost of buildings is constantly changing, so it 
must be remembered that no matter what prices are 
given in this book the estimator must in every case 
use his own judgment and true knowledge when mak- 


AND CONTRACTOR’S GUIDE 


115 

ing up his tender, and add or deduct whatever percent¬ 
age may be necessary to suit the fluctuations in prices 
of labor and materials. During the last decade the 
cost of buildings of every kind has increased from 
30 to 40 per cent; stone and the more elaborate build¬ 
ings have increased in a greater proportion than the 
cheaper kind, owing perhaps to the greater cost of 
expert labor and the more luxurious fitments. Some 
idea of the cost of a proposed building may be derived 
from a study of the proportional cost of the various 
trades. Of course the result will only be approxi¬ 
mate. For instance, in ordinary domestic buildings 
the brick work and masonry will represent from one- 
third to one half of the total cost, unless the building 
is a frame one, in which case the wood work, including 
labor and hardware, will represent about three-fifths of 
the total cost. The following figures show, from 
actual experience, about the average ratio of costs of 
the various trades for the erection of brick or stone 
dwellings with slate roofs.

Similar tables may be constructed showing the

tion of public buildings, schools, churches, theaters, 
etc., and these tables will prove of great assistance to 












ii6 


HODGSON’S ESTIMATOR 


the estimator when figuring up for buildings of a simi* 
lar nature. Having the total cost of one building of 
this kind, with the cost of each of the trades named, 
on the same building, the rest is easy, the difference 
in size and character of the two buildings being consid¬ 
ered. This may be considered estimating by compari¬ 
son. If the brick and stone work of one building costs, 
say 10 cents per every cubic foot of the building, then 
the wood work will cost, according to the rule given, 
about 8 cents and a fraction for a foot cubic of the 
whole building, and the other trades in proportion as 
laid down. 

This method is rather arbitrary, and, while given 
here, is not supposed to be quite correct, but when 
properly understood will be found quite useful. 

On the same lines I give another, which may some¬ 
times be employed in determining the cost of labor 
where all materials are furnished. This is a rough 
and ready means of making a comparison, but is pretty 
nearly correct and may sometimes be used to ad¬ 
vantage:

the labor will cost two-thirds of the same amount to 
do the work; and the same method may be applied to 
other trades. The figures must be filled in to suit the 
current prices. 

The average wages paid, at this writing, March, 
1904, according to E. M. Craig, Secretary of the 
Building Contractors’ Council, Chicago, Ill., in 29 
leading cities in the United States, are given in the 
foregoing table. The rates given are in cents per hour, 
with a few exceptions, which are given in days of nine 
hours each. 

This table will aid materially in determining the 
cost of work in and about the cities named. 

In estimating by “rough quantities,” the amount of 
materials and workmanship are first ascertained from 
the drawings and specifications in a broad and com¬ 
prehensive manner, the work being concentrated as 
much as possible, and the whole dealt with as shown 
in the previous paragraphs as this method, which see. 

Estimating by the square has been discussed 
before, but it may be briefly referred to again, as this 
method is quite common in some localities. This 
method is recommended by some authorities as being 
superior to cubing, as it gives a better idea as to the 
character of work and quality of materials, though, I 
must confess, I do not see where the advantages come 
in, for the expert “cuber” must take both those con¬ 
ditions into consideration when deciding on his “con¬ 
stant” for the cost per foot cubic of the building being 
estimated upon. In addition to what has been said 
on this method, I add the following: “The mode is 
to take the constructional shell only, pricing it at so 
much per square; walls, for instance, are taken 
according to their thickness and manner of finishing, 


120

whether they be wood, brick or stone. This must 
include all excavating, concreting, plastering, painting 
and paperhanging. The floors must include all joists, 
bridging, ceilings and ornamentations of all kinds. 
The roofs include all that is required to complete 
them, as shown on plans and described in specifica¬ 
tions, and are measured on the slope of the rafter; and 
all the other work, partitions, stairways, and every¬ 
thing in the building, must be treated in like manner, 
and all reduced to squares of 100 feet super. A price 
is then placed on each, and the whole added together. 
Such a system of superficial measurement certainly has 
some advantages, and should be fairly satisfactory, as 
it takes into account the materials and labor in a fairly 
exact manner and form. Of course, as before stated, 
a special list of prices must be compiled for each set 
of squares, the outside walls having one price per 
square, the floors another, and so on until the whole 
of the surfaces have been priced per square. It will 
be seen that care and discrimination are requisite for 
estimating by this method, or serious errors will 
occur. 

As an example of this method of estimating I 
submit the following, which is for a balloon frame 
building put up in the usuat manner, and for conven¬ 
ience a space in the building is taken for a basis of 
20 x 20 feet, making four squares. This basis may be 
taken for any portion of the work, i. e., walls, roofs, 
floors, etc. The studding employed is 2x4 inch, 
sized on one side and one edge. The studding is placed 
16 inches from centers and covered with dressed and 
matched boarding. Building paper is next laid on, 
and then first or second clear siding is used. Plates are 
included in the cost and are put on double thickness.

will be about 20 per cent. Extra price of labor will be now— 
1913—15 per cent, which add to prices ^iven.

This example gives the key to the method of esti¬ 
mating by the square, also how to estimate the cost of 
a door or window in place. 

The prices given may not be correct for any other 
place but Chicago, and even then the prices may 
differ in each ward; so the estimator must in this, as 
in all other cases, be sure of his prices before closing 
his tender. I have known the prices for door and 
window frames vary as much as 30 per cent in fac¬ 
tories not a quarter of a mile apart. 

Later on I will give other examples of estimating by 
analysis. 

ESTIMATING BY UNITS OF ACCOMMODATION 

This method of estimating does very well for certain 
descriptions of buildings, such as churches, schools, 
prisons, hospitals, asylums, stables, and buildings of a

HODGSON’S ESTIMATOR 


similar kind, but apart from these it has no value, and 
its value in the cases mentioned is not by any means a 
fixed factor. The system is based on the known cost 
of buildings which give so much space to each scholar, 
patient, sitting, horse, or prisoner. Thus, if we know 
how much a stable costs that was built to accommo¬ 
date 20 horses, it is a simple matter to estimate how 
much it cost per one horse space; for if the building com¬ 
plete cost $4,000, that would give the cost per horse at 
$200.00. So, also, with schools. If we know of a 
school for 100 children that cost $10,000, we know 
that each sitting cost $100.00; therefore it is reason¬ 
able to suppose that other schools, everything being 
equal, will cost $100 per sitting. It must not be for¬ 
gotten, however, that conditions are not always the 
same, and while a “jumped” figure of this sort may be, 
and is approximate, it is not always correct, for no 
two buildings, even though they are side by side and 
built concurrently, can possibly be built at the same 
actual cost. I have seen the attempt made on several 
occasions, and the variations amounted to from 3 to l l / 2 
per cent; quite a large amount if taken from the 10 per 
cent profits of the work. 

On occasions when time will not admit of even a 
sketch of the proposal being made, this method 
affords oftentimes the only ready means of ascertain¬ 
ing the approximate cost. Similarly, for certain 
minor accessories, when the cost of materials and 
construction varies but slightly for units of the same 
class, as in a range of latrines, etc., the approximate 
cost can be easily determined in this manner. In 
order to give the reader some basis to w'ork on, I sub¬ 
mit a few examples of price for units, which are as 
near as possible average ores for the whole of the

HODGSON’S ESTIMATOR 


Cost of theaters, complete, large cities, 

per seat.from $80 to SI 10 

Cost of theaters, small cities and towns, 

per seat. “ 48 82 

These examples are given for brick buildings of 
good style. If the buildings are of stone, from 10 to 
20 per cent must be added, according to the quality of 
the stone and amount of ornamentation. There are 
theaters in New York, Chicago, Philadelphia, and 
other large cities, that cost per seat 50 per cent more 
than I have placed in the foregoing list, but these are 
exceptions to the rule. 

If the buildings are of wood, that is, frame build¬ 
ings, then a deduction of from 10 to 15 per cent may 
be made from the figures given, which will make 
the figures approximately correct. Theaters or 
other buildings, built of bricks and stone, or of 
bricks, stone or terra cotta, cost more than buildings 
built exclusively of bricks, and provisions must be 
made for extra cost whenever this condition exists, 
and much is necessarily left to the judgment of the 
estimator in determining the extra assessment. 

ESTIMATING BY CUBING 

This method, while far from being exact, is, in my 
opinion, a more correct method than either of the 
others presented. At the same time the expert esti¬ 
mator will frequently change his constants to suit 
varying conditions. 

The following list of the cost per cubic foot, of 
buildings named, which was prepared by Mr. Kidder 
several years ago, and published in The American 
Architect , may be of some assistance to those who desire 
to know the cost of similar buildings. I may say, 
however, that it would be safe to add at this time at 
least 10 per cent on the bulk, as the prices of labor and

material have advanced sufficiently to warrant that ad¬ 
dition during the past five years. 

I have added to Mr. Kidder’s list a few others, but 
as I have been unable to get the most prominent build¬ 
ings that have been erected within the last few years, 
this table is not complete up to date, so far, at least, 
as the cost per cubic foot of the more recent buildings 
is not included.

From the foregoing table the average cost of build¬ 
ings of any description may be approximately deter¬ 
mined. The highest figures shown are those for the 
Crocker building of San Francisco, Cal., the cost per 
cubic foot being 63 cents; the lowest amounts given 
being for rough wooden sheds, barns, etc., which are 
put down at from 3^ to 5 cents per cubic foot. These 
last figures seem a little large for the kind of work 
mentioned, but they are handed me by a builder who 
has had a large experience in these kinds of buildings. 

While the foregoing deals altogether with the cubic 
foot, the same principle may be applied to yards or 
perches or any other fixed dimensions, and as an 
example I give herewith a table of miscellaneous mat-

and from actual experience, and are quite sufficient 
for the ordinary purposes of the estimator who is likely 
to purchase this book. 

As I have stated before, the cube rate cannot be 
relied upon for work of exceptional elaboration. The 
cubes generally published are intended to apply chiefly 
to buildings of a plain character in their several 
classes, and it would be of value if this circumstance 
were taken into account in fixing upon the rate. 
Precision can, however, only be attained by a general¬ 
ization from extensive experience. The rates must be 
taken as general guides in forming an estimate of cost, 
and in all cases the experience of the expert estimator 
can alone give value to the system. There can be no 
comparison between a large block of stores and an 
elaborately fitted up hotel. The one is comparatively 
simple to the other; the decoration to the hotels in an 
avenue would alone increase the cost per cubic foot. 
The materials may be the same, brick or stone, with 
the same kinds of materials for finish, but the cost of 
labor, sizes of rooms, difference in walls, in heating, 
in plumbing, etc., would make a vast difference in the 
cost per foot, as an authority says on this subject: “I 
think the probabilities are that the cubing of a building 
100 feet high would be higher than that of a building 
50 feet high. It altogether must depend upon whether 
the larger building and the higher building has rooms 
of nearly the same size as the smaller building. No 
doubt the higher building would require thicker walls, 
but immediately you get away from comparatively 
small rooms into very large cubic spaces, then the 
difference in price is not great.” 

In fewer words we may say that the cost per foot 
cube of a building depends mainly upon the divisional 


AND CONTRACTOR’S GUIDE 


137 


internal walls and floors; the more numerous the rooms 
into which the space is divided, the greater the cost. 
Height is certainly a factor of cost, as a high building 
requires thicker walls; scaffolding and labor become 
expensive. But if we take two buildings, one twice 
the superficial area of the other, but of the same 
height, the difference per foot would entirely depend 
on the interior division and elaboration of plan. But 
to say that the cubing of a bigger and higher building 
is pro rata higher than for a smaller and lower one is 
a proposition that does not always hold. It is so only 
when the rooms are about the same dimensions in both 
cases. It would, for instance, be absurd to cube a 
large public hall with the usual rooms at a higher ratio 
than a small villa residence, because it was larger or 
higher. In plain English, the greater internal space 
and vacuities the less charge must be placed on the 
cube foot. 

With regard to ornamental facades of wrought 
stone, a considerable addition per foot must be made 
upon the cost of a plain brick front. To cube both at 
the same figure would be wrong. 

It may be asked, then, would any successful builder 
take a contract on the figures derived from cubing? 
We may answer that half the estimates now made by 
architects, in their private and public capacities, are 
made by cubing, and that contractors are to be found 
who would willingly take the risk of carrying out work 
in that manner. The two most perilous rocks upon 
which the cuber comes to grief are those of taking a 
figure without the verification of experience, and not 
making any allowance for internal elaboration of plan 
and decoration.

ESTIMATING BY DETAIL QUANTITIES 

We now come to the only method on which the 
smail contractor can depend, and which is always 
reliable if the estimator only does his duty properly 
and refrains from “jumping” at the prices, a trick 
many estimators employ to evade a little work in 
figuring. 

I have given, in the first pages of this work, a 
detailed method of estimating for excavating, ditch¬ 
ing, rough walling, concreting, and other like matters, 
to which the reader is referred when he is called upon 
to estimate on such work, so I will now make a depart¬ 
ure and reproduce a system, corrected and brought up 
to date, which I published in The Builder and Wood¬ 
worker of New York, in February, 1879, and which, in 
my opinion, has never been improved. The system 
was quite popular and many thousand copies of it have 
been sold. Insurance appraisers and others have 
made it a “text-book” to some extent, and used it 
with the adjustment of prices, of course, to suit the 
time and locality. 

The list of items given in former pages must be fol¬ 
lowed, but there will be many others that will crop up 
which the estimator must provide for when preparing 
his tender, and these he should make a note of for future 
reference. It would be well to copy the items I have 
given in a good-sized book, leaving a generous margin 
for any remarks or notes it rnay be necessary to make, 
and new items should be entered as they appear. 

We will suppose the building to be figured on is to 
be a balloon frame; the total cost of it can be closely 
calculated when the price of material and wages per 
day or hour are known. 

First, mark on the plan, in plain figures, all the 


AND CONTRACTOR’S GUIDE 


139 


dimensions and measurements in the building on which 
you are to estimate. Next, get the lineal measure¬ 
ment of all the sills, and from their size estimate the 
number of feet, board measure. Retain the lineal 
measurement, as from that the labor amount is esti¬ 
mated. The labor on the sills may be summed up to 
three kinds: First, framing without gains for joists or 
mortises, for studding as in common building when 
the studding is spiked to the sills and the joists rest on 
their top. Second, with mortises for studding, gains 
for joists, or studding without mortises. Third, with 
both mortises and gains. 

Sills, 6x8, framed and placed in the building by the 
first, second and third processes, will cost for labor 
about 3, 0 and 7 cents per lineal foot. Sills, 12 x 16, 
double above prices. The intermediate sizes can be 
approximated from the above figures. 

Joists are ordinarily placed 16 inches from center to 
center, and when so placed the number of joists on a 
given floor can be found by taking £ of the length of 
the building and adding one joist where they are 
placed on top of the sill, and deducting one where the 
end sills are used in place of joist. First floor joists 
usually are 2 x 8 to 2 x 14. Second floor 2 x 8 to 2 x 12. 
Ceiling joists, where no floor rests thereon, are 2x6 
to 2x8. 

Two men will frame and place in a wood building, 
not exceeding three stories, 600 lineal feet of joists, 
in size from 2 x 6 to 2 x 14 stuff, in one day of 8 hours. 

In brick buildings not exceeding three stories, 
including anchoring and leveling up, 400 feet. Fourth 
story work, 350, and fifth story, 275 lineal feet. 

The cost per lineal foot can be had from the above 
figures. 


140 


HODGSON’S ESTIMATOR 


When joists are doubled under chimneys or parti¬ 
tions, the number of joists so used must be added to 
the result above named. 

In balloon frames no braces are used. In timber 
frames they are made as follows: 

1st. Cut off plain, spiked in, or "flat foot." 

2d. With short tenons, and 3d, with long tenons and 
pinned. Braces vary in size from 4x4 to 6x6. The 
cost of labor will not vary on account of difference in 
size. The first pieces will cost 3 cents, the second 34 
cents, and the third 44 cents per lineal foot, framed 
and placed in the building. 

The plates in a balloon frame are made of scantling 
of the same size as the studding, and are worth to 
get out and spike to the frame 2 cents per lineal 
foot. 

In timber frames the labor on plates is: (1) framing 
without braces or gains for rafters; (2) framing with 
braces and no gains for rafters; (3) framing with both 
braces and gains. An average price for labor on 
plates in sizes from 4x6 to 6x10 would be: first 
process, 3 cents; second process, 5 cents; third 
process, 7 cents per lineal foot. From 8 x 12 to 12 x 16, 
respectively, 6, 8 and 10 cents per lineal foot. This 
includes placing them in the building. Plates laid on 
walls are worth the same as plates spiked on the 
joists. 

Posts in balloon frames are merely double-studding. 
The cost of placing them in position is the same as for 
studding. 

Posts for timber frames are framed, first, with tenon 
top and bottom; second, the same, with one set of 
braces with girth or beam mortises; and third, the 
same, with two sets of girth or beam mortises. 


AND CONTRACTOR’S GUIDE 


141 

By the first process posts from 4 x 6 to 8 x 10 would 
cost 6 cents. Second process, 8 , and the third proc¬ 
ess,10 cents per lineal foot to frame and place in the 
building. 

Studding for balloon frames is usually placed 16 
inches from center to center. They vary in size 
from 2 x 4 to 2 x 6 . Occasionally odd sizes are used, 
as 2 |x 4, 2x5, or 3x4. In an ordinary size 

frame building two men will lay out and raise 800 
lineal feet of 2 x 4 studding per day, or 750 feet ot 
2x6. 

At $4 per day, the first would cost $ 1.00 per 100 
lineal feet. The latter, $ 1 . 20 . The labor of spik¬ 
ing of joists and plates being considered under their 
respective heads, the work on studding is simply con 
fined to tenoning and studding on end, or spiking them 
to the sills. 

A short rule for getting the number of pieces of out¬ 
side studding, including plates, and allowing for 
doubling at all corners, and for windows and doors, is 
simply had by allowing one piece of studding for 
every foot of outside measurement. 

This rule for buildings having many angles, where 
studding must be doubled, approximates very closely 
to the true result. In smaller buildings, without any 
angles, it will somewhat overrun. 

o 1 

The exact number of pieces of studding on the out¬ 
side of building may be found by taking three-fourths 
of the number of feet in the outside measurement or 
the building; add one stud for each corner and angle, 
and one for each door and window. To this add for 
plate and gable studding. 

Three-fourths of the number of lineal feet of all 
partitions will give the number of pieces required. 


142 


HODGSON’S ESTIMATOR 


Their length, of course, depends upon the height of 
the rooms. 

The cost of labor is the same as for outside stud- 
ding. 

It frequently happens that the studding is not double 
for doors and windows, and occasionally the extra stud 
for the corners in omitted. 

Ribs for studding are usually made from 1 to 14- inch 
stuff, and will cost to lay out and nail to the studding 
about 1 cent per lineal foot. The purpose for these is 
to support the upper joist. 

Three-fourths of the width of the building, less one, 
gives the number of pieces required for gable; the 
average length of each piece is the distance from the 
plate to the ridge of the roof, or what is termed the 
rise of the rafter. 

Rafters are designated as main or principal rafters, 
hip, jack, and valley rafters, and plain rafters. 

The long rafters of a hip roof are called the main or 
principal rafters. 

The shorter ones are called jack rafters. 

A plain rafter is the ordinary rafter used in straight 
gable roofs. 

The projection of a rafter is the distance it extends 
boyond the plate, or the length of the look-outs. 

The rise of a rafter is the height on a perpendicular 
line from the plate to the ridge of the roof. 

The gain of a rafter is the difference between the 
run and its length. 

The run of a rafter is the distance from the outer 
edge of the plate to a point immediately under the 
ridge of the roof, or one-half the width of the build¬ 
ing. 

For a common rafter, to the square of the rise, add 


AND CONTRACTOR’S GUIDE 


M3 


the square of the run. The square root of their sum is 
the length of the rafter from the outer edge of the 
plate to the ridge of the roof. 

The rise of a rafter is found by multiplying the num¬ 
ber of inches rise required by the run by one-half the 
width of the building. 

The rise in one-quarter pitch is one-quarter the width 
of the building. In a one-third pitch, one-third the 
width of the building. In a one-half pitch, one-half 
the width of the building, etc. 

A common rafter can also be found as follows: 
If the roof is one-quarter pitch, to the square of one- 
quarter of the width of the building add the square of 
one-half the width of the building. The square root 
of the sum will be the length of rafter required. If a 
roof is one-third pitch square, one-third of the width 
of the building. If one-half pitch square, one-half the 
width, etc., and then proceed with the balance of the 
rule. 

Required the length of rafters for a building 24 feet 
wide, gable roof, and one-quarter pitch. 

One-fourth of 24 equals 6; \ of 24 is 12. Squaring 
both gives 36 and 144, or 180; the square root of which 
is 13.416 feet, or length of rafter required. 

Rule for estimating the length of rafters for hip 
roofs where they are of equal lengths: 

Get the length of the main rafter by using the rule 
for common rafters. Then divide the length of the 
main rafter into one more space than the number of 
rafters required. The length of the space is the length 
of the shortest jack rafter, and the length cf each 
studding rafter is simply the space added to the length 
of the preceding one. 

Example.— Main rafter, 24 feet. Number of jack 


144 


HODGSON’S ESTIMATOR 


rafters required, 7. Hence the number of spaces wouid 
be 7 + 1, or 8. Dividing 24 by 8 gives 3 feet as the 
length of the shortest rafter. The next would be 6 
feet, then 9 feet, 12 feet, 15 feet, 18 feet, 21 feet, and 
then comes 24, or the main rafter. 

Common rafters on shingle roof are placed from 1G 
to 24 inches from center to center, according to the 
length and weight of roof required; generally 2 feet is 
the distance. 

The number of rafters in a plain gable roof is found 
by dividing the length of the building by the distance 
the rafters are apart from center to center, to which 
add 1; the result is the number of pairs of rafters. 

Cost of Framing Rafters.—Two men in one day will 
frame and place in the building GOO lineal feet of 2 x 4 
or 2 x 6 rafters—roof, plain gable. 

In a hip roof, including framing for deck, if any, 250 
feet is a fair day’s work. 

The former would cost $1.00 per 100 lineal feet, and 
the latter $2.10 per 100 lineal feet. 

The contract price for framing one and a half, two, 
md two and a half story houses, in many of the West¬ 
ern states, averages $1.15 per 100 lineal feet of all the 
bill timber. 

In all the framing labor thus considered, reference 
is had to soft wood only. If hard wood is used a fair 
addition to the prices would be 40 per cent. 

If any of the work is circular, segment or octagonal, 
an addition must also be made, varying from two to 
fcur times the prices herein charged. 

Lookouts for Hip Roofs. —An average length would be 
20 inches. These are made of inch stuff and nailed to 
the rafters. They are worth, to get out, furnish mate¬ 
rial and place in position, 22 cents each. 


AND CONTRACTOR’S GUIDE 145 

\ 

The siding to a building is either drop siding, lap 
siding, dressed barn boards, or rough barn boards. 

The number of feet of drop or lap siding is found by 
multiplying the outside measurement of the building 
by the height of the posts, to which add for gables, if 
roof is a gable roof, the product of the width of the 
building by the height from the plate to the ridge of 
the roof. This gives the number of surface feet, to 
which add one-fifth for lapping, and you have the 
number of feet board measure. 

Two men will put on 700 feet in one day of drop 
siding when the window-casings and corner-boards are 
placed over the siding. Where joints are made 
against casings and corner-boards, 400 to 500 feet is a 
day’s work. 

Of lap siding, 050 feet. This includes putting up 
staging. Making the prices per square: Drop siding 
by the first method, $1.00; second method, $1.40 to 
$1.50. Lap siding, $ 1 . 20 . 

Two men will put on 2,000 feet of rough barn boards, 
or 1,500 feet of surfaced barn boards in one day, and 
will put on 2,000 feet of dressed battens, or 3,000 of 
rough battens. Hence the price would be: rough barn 
boards, 35 cents per 100 feet or one square; surface 
barn boards, 40 cents per 100 feet or one square. 
Dressed battens, 35 cents per 100 lineal feet. Rough 
battens, 25 cents per 100 lineal feet. 

Roofs.—The area of a plain gable roof is had by 
multiplying the entire length of the rafters by the 
length of the building, including the projection of the 
cornice This gives one side; doubling it gives the 
total square feet of roof. 

Hip Roofs.—Get the entire outside measurement of 
the building, including the projections of the cornice. 


146 


HODGSON’S ESTIMATOR 


Multiply this by the length of the principal rafter and 
take one-half; the result is the area of the root. 

Hip Roof with Deck.—To the outside measurement of 
the deck, add the outside measurement of the building 
as above. Multiply this by the length of the principal 
rafter, and take one-half for the area of the roof. 

Roof boards for plain gable roofs are worth 50 cents 
per square to put on the building, and for hip roofs 75 
cents per square. 

If roof boards are matched stuff for tin or slate roof, 
charge SI.25 per square for gable and SI.50 per square 
for hip roofs. 

Shingles.—The average width of a shingle is 4 
inches. Hence when shingles are laid 4 inches to the 
weather, each shingle averages 16 square inches; and 
900 are required for a square of roofing. 

If 41 inches to one another, 800 will cover a square. 

If 5 inches to one another, 720 will cover a square. 

If 51 inches to one another, 655 will cover a square. 

If 6 inches to one another, 600 will cover a square. 

This is for common gable roofs. In hip roofs, 
where the shingles are cut more or less to fit the roof, 
add 6 per cent to above figures. 

A carpenter will carry up and lay on the roof from 
1,500 to 2,000 shingles per day, or 2 to 24 squares of 
plain gable roofing, so that an average price per square 
for simply laying the shingles would be $1.75. Add 
50 cents for laying the roof boards, and the labor 
account on a common shingle roof would be $2.20 per 
square. 

Tin Roofs.—A sheet of roofing tin is 14 x 20 inches, 
and a box of tin contains 112 sheets. 


AND CONTRACTOR’S GUIDE 


H7. 

Allowing the usual amount for side ribs and top and 
bottom laps, a box of tin will cover 182 square feet, 
and is worth about $7.00 per box. 1 C. charcoal. 

Laying a box of tin will cost as follows: 


1 box 1 C. charcoal tin. $7.00 

10 pounds solder. 2.00 

Preparing tin for roof. 2.00 

Laying tin, 1 1/5 days. 5.00 


Valleys.—Tin valleys for shingle roofs are generally 

14 inches, and for slate roofs 20 inches wide. An 

average price put on the roof, including material, 

would be 16 cents per square foe-:. One man will lay 
1J squares per day of valleys, in plain work; when 

roof is steep or valleys cut up, 1 square is a day’s 
work. 

Flashings.—Tin flashings for chimneys and where 
one part of a building joins another are worth, put on, 

15 cents per square foot. 

Gutters and Spouts.— 

Gutters, 4-inch, are worth, put up, 16 cents per lin. foot. 
Gutters, 5-incli, are worth, put up, 18 cents per lin. foot. 
Gutters, 6-inch, are worth, put up, 20 cents per lin. foot. 
Down spouts, 2-inch, are worth, put up, 14 cents per lin. foot. 

Down spouts, 3-inch, are worth, put up, 16 cents per lin. foot. 

Down spouts, 4-inch, are worth, put up, 18 cents per lin. foot. 

Down spouts, 6-inch, are worth, put up, 35 cents per lin. foot. 

Slate Roofs.—The price per square for slate roofs 
can be had of slaters in any of our towns and cities. 

They will vary from $10 to $11 or $14 to $20 per 
square. 

The following table will be found useful to the esti¬ 
mator.

The above sizes sometimes slightly vary, according 
to the quarry. 

Slates are classed according to their straightness, 
smoothness of surface, fair even thickness, presence 
or absence of discoloration, etc. They are generally 
divided into first and second qualities, and in some cases 
a medium quality is quoted. Slates of first quality 
are thinner and lighter than those of inferior quality. 

Rule to find the number of slates required to cover 
one square: One square in inches + width of slate in 
inches x gauge in inches. 

The weight of slating on roofs is 8 pounds per foot 
super, for all sizes, except rags or queens, including a 
3-inch lap and nails. 




































AND CONTRACTOR’S GUIDE 


149 


As there are two nails per slate, the number required 
per square will be found by doubling the number of 
slates. The trade “thousand,” or “long tally,” equals 
1,200 for buying and selling. 

Nails.—Composition nails are best for all good work, 
as they are stiff and tough. They are cast from an 
a] oy of 7 copper to 4 zinc, and have a yellow, brassy 
appearance. Copper nails are either cast or wrought; 
but they are soft and dear. Malleable iron nails are 
frequently used, dipped while hot in boiled linseed oil 
to preserve them from corrosion. These can also be 
painted or galvanized. Cast-iron nails are only 
employed for temporary work. Zinc nails are very 
soft, and liable to bend, and as their heads come off in 
driving, they make a good deal of waste. 

All these nails are sold by weight, and the price 
should lessen with the increase of length. Allow 5 
per cent for waste in reckoning the number to the 


square. 

Nails for small slates, such as Doubles, etc., 

should be about. If in. long 

Nails for medium slates, such as Countesses, 

etc., should be about. 1 \ in. long 

Nails for large slates, such as Duchesses, etc., 

should be about. 2 in. long

These prices vary with time and locality. 


Labor.—The labor in holing slates, any size, is 
usually estimated at $2.00 per thousand; but if a single

150 

slate-holing machine is used, a smart boy, at 15 cents 
per hour, will be able to hole from 300 to 400 slates in 
an hour. 

The following statement shows the labor required 
per square, which will be less for larger surfaces, as the 
slating will be performed more quickly. The differ¬ 
ence in time for the various kinds represents the extra 
trouble in handling, greater areas being covered with 
larger slates in a given time, and the labor in holing is 
the same for all sizes.

square), will give the number of slates to a square—• 






AND CONTRACTOR’S GUIDE 


151 

e.g., 84 inches gauge by 10 inches breadth of slate = 85 

, . , 14,400 super, in. per square 

square inches margin, and - -r- 1 - - - 

bo sq. in. margin per slate 

= 170 Countess slates per square. 

Allowing 5 per cent for waste, this would give 
roundly 180 slates to the square. 

As there are two nails per slate, the number of nails 
required per square will be found bv doubling the 
number of slates—i. e., in this case, 340 nails. Also 
reckoning 5 per cent waste for nails, the number for 
estimating would be some 360. Using 1^-inch compo¬ 
sition nails, 144 of which go to the pound, this latter 
number would give exactly 2^ pounds per square, as 
they are sold by weight. 

A slate roof is laid by first placing a course on the 
eaves. All courses above this one must be laid with a 
lap of more than one half the length of the slate or the 
vertical joints which are not close will not be covered. 
The lap of the slate is more than one-half its length, 
so the more lap a course is laid with, the better will be 
the roof. Manufacturers allow 3 inches when selling a 
square of slate, and architects and consumers should 
see that the roof is laid with that amount of lap, as a 
less one is a considerable gain for the dishonest roofer, 
which he takes advantage of to the permanent injury 
of the roof, because any less lap than 3 inches greatly 
endangers the weather-proof qualities of a slate roof. 
Slate, before it is laid, should be carefully sorted, the 
thick ones used to start the roof at the eaves and 
the thin ones to finish with at the comb. In nailing 
slate do not drive the nails too tight. The top of 
the nail should be just even with the surface of the 
slate.

Cornices. —An ordinary plain cornice has three mem¬ 
bers, viz.: frieze, soffit, and fascia. 

The frieze is the part nailed or fastened to the side 
of the building. 

The soffit is the part attached to the under side of 
the projection of rafter, or lookout. 

The fascia is the part attached to the end of the raft¬ 
ers or lookout. 

Crown moulding is the moulding on the fascia. 

Bed moulding is the moulding in the angle where 
the frieze and soffit join. 

In estimating the amount of material in a given 
cornice for a square roof, multiply the entire outside 
measurement of the building by the sum of the width 
of the soffit, frieze and fascia; the result is the number 
of feet, board measure. 

For gable roofs, to the lengths of the two sides of 
the building add the end projections and length of end 
rafters and multiply as before.

Two men will dress six squares of flooring after laying 
per day, or at a cost of $2.00 per square. 


AND CONTRACTOR'S GUIDIi 


155 


If flooring is of hard wood, estimate per day two- 
thirds of above. 

The number of feet, board measure, in a given floor 
is had by multiplying its length by its width and add¬ 
ing one-fifth for lapping. For flooring not matched 
omit the lapping. Two men will lay 1,333 feet of plank 
flooring per day, or 50 cents per square, or will lay 
2,000 feet of common rough flooring, 1-inch stuff, or 
50 cents per square. 

Outside ceiling for wood buildings, average width, 
including beading and scaffolding, is worth, to put up, 
$1.50 per square. An average day’s work for two men 
is five squares. Two men will dress, after laying the 
ceiling, five squares per day, or $1.45 per square. 
Ceiling overhead is generally of wider stuff than out¬ 
side ceiling; as there is no beading, and the workman¬ 
ship is not so particular, two men will put up the same 
amount as of outside ceiling, including putting up and 
taking down scaffolding, or five squares at $1.00 per 
square. 

Wainscoting.—Wainscoting 2J to 3 feet high, beaded, 
with ordinary capping, including dressing after putting 
up, is worth $6.00 per square. Two squares is a day’s 
work for two men. 

The same, 3 feet to 4 feet high, is worth, to put up, 
$5.00 per square. 

The same, with shoe and heavy caps, is worth $4.00 
per square. The capping to wainscoting is ordinary 
moulding from 1-J- inches by $ to 2 inches by 1J- inches, 

Panel wainscoting, mill worked, ready to put up, 
including capping, shoe or base, is worth, for labor, 
$5.00 per square. 

Hand-worked panel wainscoting is of so various a 
kind that definite prices of labor cannot well be given

without specifications. In a general way, the, price 
per square for getting out and putting up will vary 
from $6.00 to $30.00 per square. 

The above prices are for soft wood. For hard wood 
add 40 per cent. 

Baseboards.—Plain base, 6 to 10 inches wide, put up 
before plastering, is worth 3 cents per lineal foot for 
labor. Two hundred feet is a good day's work for a 
man with mill-dressed lumber. 

The same, put on after plastering, including putting 
on grounds, is worth 4 cents per lineal foot. 

Plain base, after plastering, with moulding, leveling, 
or capping by hand—mill-dressed stuff—is worth 4 
cents per lineal foot to get out and place in the 
building. 

Stairs.—The wall string is the board with which the 
ends of the steps are fixed next to the wall. 

The face string is the board that carries the outer 
end of the steps and risers. 

The tread is the horizontal board of the step. 

The riser is the upright board of the step. 

The newel post is the upright post at the lower step 
to receive the hand rail. 

The hand rail is the rail supported by balusters. Bal¬ 
usters are small columns or pillars to support the rail. 

The number of risers is found by dividing the dis¬ 
tance from floor to floor by the height of the rise. 

The height of each rise is found by dividing the dis¬ 
tance from floor to floor by the number of risers. 

The number of treads is one less than the number of 
risers. 

The width of each tread is found by dividing the 
risers by the number of treads and adding the 
projection. 


AND CONTRACTOR’S GUIDE 


157 

Risers vary in height from 4 to 8 inches. Treads 
run from 8 to 14 inches. 

It will be impracticable to give detail prices for all 
variety of stair-work on account of the diversity of 
designs. We simply give a few as an illustration. The 
labor on rough, open stairs, for cellars or stables, when 
no risers are used, is worth 18 cents per tread. Straight 
stairs between partitions, 2 feet 6 inches to 3 feet 6 
inches long, with 6-inch to 9-inch tread, and 7-inch to 
8 -inch risers, are worth 40 cents per riser. 

Winding stairs, same dimensions, 40 cents per riser. 
Open straight stairs, risers 6^4 to 8 inches, treads 6 to 

11 inches; housed in wall strings, mitered to face string; 
moulded nosing, including putting up turned balusters, 
and plain round or oval rail, with 6-inch to 8-inch 
turned newel post, are worth for labor $2.50 to 
$2.75 per riser. 

The same stairs, winding, charge $3.75 per riser for 
the winding steps, and $2.50 for straight steps. Putting 
on brackets outside of stringer is worth from 5 to 25 
cents per bracket. 

The following is a list of the approximate prices of 
stair material: 

Newel Posts.—A turned newel post of cherry or 
black walnut, 5 inches in diameter, with cap, is worth 

$5.00; 6 inches, $6.00; and 8 inches, $7.50. 

Octagon newel posts, walnut, oak, or cherry, with 
ornamental cap, 8 inches, $10.00; 9 inches, $11.00; and 

12 inches, $12.00. 

Newel posts veneered with fancy woods, with carv¬ 
ing on plinth and cap, and moulded sunk panels, will 
vary from $20.00 to $60.00 each. 

Balusters.—Turned balusters, walnut or cherry, 
from 2 feet 4 inches to 3 feet, are worth, 1 y 2 inches, 20

cents; 2 inches, 22 cents; and 2 l / 2 inches, 28 cents each. 
Oak and ash 20 per cent less. 

Fluted or octagon balusters, walnut or cherry, 2 inches, 
25 cents; 2 l / 2 inches, 35 cents; 2TJ inches, 40 cents each. 
Fancy balusters for high-priced stairs may run from 40 
to 80 cents each. 

Rails.—Walnut or cherry, 3^4-inch, 25 cents; 4-inch, 
30 cents; 4^4-inch, 35 cents; and 5-inch, 35 cents per 
lineal foot. Raised back rails, walnut or cherry. 4-inch, 
35 cents; 5-inch, 40 cents; 53 / 2 -inch, 45 cents; and 6 -inch, 
50 cents per lineal foot. Fancy raised back rails 
from 6 to 7 inches will vary from 50 cents to $1.00 per 
foot. 

Doors.—The price of doors may be had from any 
dealer’s catalogue. The labor account is as follows: 
A fair day’s work for one man is setting 5 door frames 
a day, and putting on ordinary casing. He will also 
hang and finish 5 doors per day, or $1.20 a door com¬ 
plete. The above is for 6 feet to 7 feet 6 inch doors, 
and 1 % inch thick. From 7 feet 6 inch to 9 feet doors 
and 1 % inch thick, a day’s work of setting and casing 3 
frames per day, or hanging and finishing 3 doors per 
day, $ 2.00 per door complete. 

Moulding Door Casings.—For 6 feet to 7 feet 6 inch 
doors, and 3-inch mouldings, one man will mould 6 
door casings, two sides, per day, or $ 1.00 per door; 
with 4%-inch mouldings, 5 doors per day, or $1.20 
per door. Mouldings with two members about one- 
half above number, 7 feet 6 inches to 9 feet doors, 
single moulding two sides, 5 openings per day. The 
same, with double members to moulding, 2 1 /-} openings 
per day. 

Door frames when had from factorv are cased both 
sides for inside doors, and one side for outside doors 


AND CONTRACTOR’S GUIDE 


159 


Sliding Doors.—The frames for a pair of sliding 
doors with double joint, including casings each side, are 
worth from $6.50 to $7.00 per frame. 

The same, with segment top, will vary from $6.00 
to $12.00; setting either one of the above frames, put¬ 
ting up the track, and lining the pocket is worth from 
$3.50 to $6.00 for labor. Setting, hanging, and trim¬ 
ming a pair of sliding doors will take a man about 1J4 
days, or $9.00 per door. 

Folding Doors.—The frame for a pair of folding 
doors with opening 5 feet by 8 feet 6 inches, with single 
joints, including casing each side, is worth from $4.50 
to $8.25 per opening. Segment top, same size open¬ 
ing, $6.00 to $10.00. Setting the frame for a pair of 
folding doors will take a man three-quarters of a day, 
or $4.50 per frame. 

Fitting, hanging, and trimming a pair of folding- 
doors will take one man a day and a quarter, or $7.25 
per door. 

Moulding, sliding and folding door casings, square 
top opening 5 feet by 8 feet 6 inches on both sides, 
single member; a day’s work is 4 openings per day, or 
$1.50 per door. If moulding is double member, 
two openings per day, or $3.00 per door. Segment top 
with same size of swing, the moulding will cost $6.00 
per opening. Over the face of a square top, one man 
will put on the moulding with a single member in one- 
half a day, or $3.00 per opening. Double member one 
day, or $6.00 per opening. 

Setting door frames in brick buildings will cost the 
same as for frame buildings. 

Common Door Frames.—Outside frames with cas¬ 
ings on one side for doors, from 2 feet 6 inches by 6 feet 
6 inches to 2 feet 8 inches by 6 feet 8 inches, are worth 


HODGSONS ESIMATOR 


i Go 

from $3.25 to $4.50 each. The same for inside doors, 
with casing on both sides, are worth from $6.00 to 
$7.00. 

Door Trimmings.—Butts 3x3 inches, for cheap 
trimmings, are worth 10 cents per pair, and a common 
mortise or rim lock, with brown knob, 30 cents each. 
3 x Si/o butts, 10 cents, and 3*4 x 3%, 10 cents eacli; 
4x4, 15 cents. A good mortise lock, with brown or 
white knobs, brass key, face, and bolt is worth 50 cents. 
Outside door locks vary from 50 cents to $4.00 a pair; 
average price would be $1.50. 

Sliding door locks 4x5, brass key and face, $2.50 
each. Iron track for door, 3 cents per foot; brass 
track, 25 cents. A very good rabbeted lock, without 
night works, $1.50; with night works, $3.50 to $4.50 
each. 

Screws for putting on above trimmings, 30 cents a 
gross. The labor account for trimming doors will be 
found under the head of doors. 

Windows.—The price of the sash, including glass 
and glazing for all sizes of windows, may be had from 
the dealers’ catalogues. Window frames, factory 
made, simply have outside casings and jambs. One 
man will cut the openings and set five frames per day; 
of an average size, say 2 feet 6 inches by 6 feet, in a 
frame building, and can set the same number in a brick 
building, or $1.20 per opening. 

As the brick-work goes up the carpenter must plumb 
up the frames occasionally, so that a fair estimate 
would be both alike. 

In larger openings, setting from two to four frames 
per day would be fair work, or from $1.20 to $1.50 per 
window. 

One man will case 12 windows per day of windows 2 


AND CONTRACTOR’S GUIDE 


161 


feet 6 inches by 6 feet, or 3 cents per lineal foot of 
the casing. 

Moulding window casings, same price per foot as 
door casing. 

For wood buildings, plain rail sash, 8 or 12 lights, 
with outside casings, an average price would be as 
follows: 

8 x10, $1.20; 10x12, $1.50; 10x14, $1.80; 10x10, 
$2.20. 

With check-rail sash outside, casings : 8 x 10, $2.00 ; 1U 
x 12, $2.50 ; 10 x 14, $2.70 ; 10 x 16, $3.00 ; 10 x 18, $3.25. 

Plain window frames for brick buildings: 8 x 10, 
$2.00 ; 10 x 12, $2.20 ; 10 x 14, $2.50 ; 10 xl6, $2.60 ; 12 x 
24, $3.65. 

Box window frames: 8x10, $3.25; 10x12, $4.00; 
10 x 14, $4.20 ; 10 x 16, $4.50 ; 12 x 24, $4.80. 

The same frames, with segment outside and square 
inside, are worth 50 cents more. 

Pantries and Closets.—In ordinary work of this kind 
one man will get out and put up 50 to 75 lineal feet of 
shelving 12 inches wide per day, or will make and put 
up five drawers 15 inches wide by 18 inches deep, in¬ 
cluding racks and fitting. 

If the drawers are dovetailed, four is a day’s work. 
Strips and hooks: one man can put 50 to 80 lineal 
feet of strips, and put on closet hooks, about 12 inches 
apart, in one day. 

Porches.—These differ so widely in design that prices 
per foot lineal cannot be given without specifications, 
as they will vary from $2.25 a foot upwards. In an 
ordinary porch, figure the sills and joists as in framing; 
also roof, labor, ceiling, and cornice the same as in 
other parts of the building, and charge for whatever 
extra work the design may call for.

HODGSON’S ESTIMATOR 


Blinds.—These are made and sold by the foot, meas¬ 
uring height of the window on one side only; 80 to 90 
cents per lineal foot, including trimming and hanging, 
is a fair price. Inside blinds, O. G. panel or rolling 
slats, ordinary width, are worth $1.50 per foot, com¬ 
plete in the building. If inside blinds are of hard 
wood, they are worth from one and a half to double 
the price of pine. 

Plastering.—The number of yards is simply the area 
of all the walls and ceilings. 

One hundred yards of plastering will require 1,400 
laths, 4% bushels of lime, 18 bushels of sand, 9 pounds 
of hair, and 5 pounds of nails for two-coat work. 

Three men and one helper will put on 450 yards, in 
a day’s work, of two-coat work, and will put on a hard 
finish for 300 yards. 

Retail cost of three-coat work for 100 yards of 
plastering: 

Seven bushels of lime. 

Four-fifths of a load of sand. 

Nine pounds of hair. 

Five pounds of nails. 

Lathing, 100 yards. 

1400 laths. 

Plastering, 2 coats, 1 man § of a day. 

Helper, l of a day. 

Hard finished, one day’s work. 

Making mortar and scaffolding. 

Or, say twenty-eight cents per yard. 

Painting.—Painting is done by the yard, and at the 
present prices of lead and oil, house painting in plain 
colors will cost on an average: 

For one coat, 10 cents per yard; two coats, 18 cents 
per yard; three coats, 28 cents per yard. 


AND CONTRACTOR’S GUIDE 


163 


One coat, or priming, will take for 100 yards of 
painting 20 pounds of lead and 4 gallons of oil. Two- 
coat work, 40 pounds of lead and 4 gallons of oil. 
Three-coat, the same proportion; so that a fair esti¬ 
mate for 100 yards of three-coat work would be 60 
pounds of lead and 12 gallons of oil. 

A day’s work on outside of a building is 100 yards of 
first coat, and 80 yards of either second or third coat. 
An ordinary door, including casings, will on both sides 
make 8 yards to 10 yards of painting, or say, 5 yards 
to a door without the casings. An ordinary window 
2\ to 3 yards. Fifty yards of common graining is a 
day’s work for a grainer and one man to rub in. 

In measuring up outside work, use the rule for plain 
surfaces. In common painting run your tape-line over 
all the mouldings in and out, and this, with the width 
of the cornice multiplied by its length, will give the 
area. It is customary to add from one-third to one- 
half for the bracket painting. In painting blinds of or¬ 
dinary size, twelve is a fair day’s work for one coat, and 
9 pounds of lead and 1 gallon of oil will paint them. 
In measuring up inside base, it is customary to reckon 

9 inches in width and upwards to 1 foot as 12 inches. 

Nails.—One thousand feet of inch stuff will require 

10 pounds of 10-penny nails; 1 square of siding or ceil¬ 
ing, 24 pounds 8-penny, and the same for a square of 
roof boards or sheathing, and 1,000 shingles will take 
G pounds of shingle nails. 

Brick and Stone Work.—A day’s work in excavating 
and filling into cart or wheelbarrow is 11 or 12 cubic 
yards of common earth, or 7 to 8 yards of clay 01 
coarse gravel, or 17 to 20 cents per yard. In limestone 
or sandstone a day’s work in quarrying will range 
from one-half to one cord of stone. 


164 


HODGSON’S ESTIMATOR 


Stone Work.—A perch is 16% feet long, 1% feet 
wide, and 1 foot high, and contains 24% cubic feet. In 
estimates 25 cubic feet is figured as a perch. 

A perch in the wall contains about 22 cubic feet of 
stone and 3 cubic feet of mortar. 

The waste ordinarily allowed in laying stone walls 
from the rock measurement is one-fifth. 

A cubic yard of rubble masonry laid in the wall con¬ 
tains 1 1-5 cubic yards of undressed stone and one- 
fourth of a cubic yard of mortar. 

Four perches or 100 cubic feet of wall will contain 
ordinarily 1 cord of stone or 128 cubic feet, 1 barrel of 
lime, or say 2% bushels, and 5 barrels of sand. 

A day's work for a mason’s helper is moving 4 to 5 
perches of stone, and mix and carry to the mason suffi¬ 
cient mortar to lay them. 

A man will lay in one day from 4 to 5 perches of 
rubble masonry in sandstone, or 3 perches in limestone. 
In many locations sandstone is delivered for $1.50 per 
perch, and the labor for laying in ordinary walls, in¬ 
cluding lime and sand, from $1.00 to $2.00 per perch. 

Stone Ashlars.—These are ordinarily 3 feet to 5 feet 
long, 1 foot high, and 4 to 6 inches thick. 

I4ie price of the rough stone will vary according to 
locality. The labor on ashlars, including setting, is per 
square foot as follows: 

Fine posts, kammerwork, limestone, 35 ets.; sandstone, 30 cts. * 

Medium “ “ 30 “ “ 27 “ 

Hough 11 11 25 ( ‘ 1 ‘ 22 (i 

Freestone ashlars, sawed, are furnished at the mills 
for 35 to 50 cents per square foot, and caps and sills 
for ordinary windows and doors from $2.25 to $3.00 
each. 

Brick Work.—The labor and material of brick work 


AND CONTRACTOR’S GUIDE 


165 


are estimated by the 1,000 brick. In measuring up 
brick walls it is not customary to deduct for openings. 
To ascertain the number of bricks in a wall: First 
obtain the number of superficial feet, and multiply this 
by 7 for a 4-inch wall, by 14 for a 0-inch wall, 22 for a 
14-inch wall, and 20 for an 18-inch wall. If thicker than 
18 inches, for each additional 4J inches in thickness 
add 7 bricks per square foot. 

One thousand five hundred brick is an average day’s 
work for outside and inside walls, and we take three- 
quarters of a barrel of lime and 0 bushels of sand to 
make the mortar. The number of brick a mason will 
lay in a day on a plain wall depends largely upon its 
thickness. On 0-inch work, 1,200 to 1,400; on 14-inch 
work, 1,500 to 2,000, and on 18-inch work, 2,000 to 
2,500; veneered work or single-back walls attached to 
wood work is much slower, from 400 to GOO brick is 
regarded a day’s work; this includes tying the brick 
with nails to the framework, or sheathing. 

The following is given as an illustration of the cost 
of furnishing and laying 1,500 brick, or one day's work. 

1500 brick. 

£ barrel of lime. 

9 busliels of sand. 

1 day’s work for mason. 

1 day’s work for helper. 


Chimneys.—Common flues and ordinary chimneys are 
worth from $1.00 to $1.50 per running foot, including 
labor and material. In large chimneys with fire¬ 
places, get the number of brick, charge for lime and 
sand the same as in brick walls, and estimate the labor 
at double the price of plain walls of same thickness. 


HODGSON’S ESTIMATOR 


166 

Plumbing.—In plumbing for bath-rooms and closets 
IJ-inch pipe is used for water, f-inch for supply, and 
4-inch iron pipes for soil-pipe. An average price 
would be for material and putting in the building: 
lj-inch pipe, lead, 50 cents per foot; f-inch pipe, lead, 
40 cents per foot, and soil-pipe, 45 cents per foot. 

Bath-tubs will vary in price from $15.00 to $50.00; 
double bath-cocks, $12.00 to $15.00; single, $1.90 to 
$3.00; wash-bowl cocks, from $2.00 to $3.00. 

A fair price for a corner wash-bowl, marble, with 
stop-cocks and enclosed with casings, including con¬ 
nections with pipes, will vary from $12.00 to $20.00; 
water-closet basins and connections, $6.00 to $8.00. 

It must be understood that the foregoing prices are 
only approximately correct. 

SOME painter’s EXTRAS 

In estimating the painter’s work, a few facts and 
data as to the quantity of paint required to cover cer¬ 
tain areas of surface are necessary. Thus it is useful 
to know that 1 pound of mixed white lead paint will 
cover about 4J superficial yards the first coat, and 
about 6^ yards each additional coat; that 1 pound of 
mixed red lead paint will cover about 5| yards super, 
of iron. Some authorities say 45 yards of first coat, 
including stopping, will require 5 pounds of white 
lead, 5 pounds of putty and 1 quart of oil; and 45 
yards of each succeeding coat will require 5 pounds of 
white lead and 1 quart of oil. These quantities do not 
exactly agree, but they are approximately correct, and 
we may take about 6J to 7 yards to be about a fair 
allowance for 1 pound of paint; if the paint costs, say, 
15 cents per pound, the cost would be about 2J cents 
per yard for material; 1 pound of mixed white lead 


AND CONTRACTOR’S GUIDE 


167 


paint will cover 1 yard super, on Portland cement (first 
coat); good oil varnish requires 1 pint to 8 or 9 yards 
superficial, one coat. 

In measuring the painting of iron railing, the two 
sides are measured as flat work, both sides plain, and 
charged as such, unless gilded; if the railing is delicate 
and ornamental, the charge is once and a half, or twice 
is taken for each side. 

The rotation in taking the items are generally the 
windows, base dadoes, chimney pieces, doors; but this 
rule is not strictly observed, and in the abstracting the 
one-coat work comes before the three, four, or five 
times in oil; flatting and ornamental work follow the 
plain painting. 

It may be useful to remember that the decimal .27 
multiplied by the rate of wages for a painter per hour 
will give the cost per yard for common work, including 
stopping, knotting, etc., and the decimal .15 for second 
and following coats. 

Staining, sizing and varnishing taken at per yard 
superficial should be described as to stain and the num¬ 
ber of coats of varnish. For varnished work, state if 
on natural wood or painted. Graining and varnishing 
at per yard is similarly measured to plain painting, and 
should be described as “extra”; state if “combed,” 
“once grained,” and varnished, and the wood to be 
imitated as oak, walnut, etc., if once or twice var¬ 
nished, and if with spirit or copal, if the wood is to be 
sized.

THE PLASTERER AND PAINTER 

In estimating for plastering, or for painting also, 
(1) the description of all materials and work should be 
kept separate. (2) Plastering on walls to be measured 
from the floor upwards, or from the point where each 
description of work commences. (3) Where cornices 
are lathed on brackets, measure ceiling and walls to 
the edge of the brackets only. (4) Where cornices are 
not bracketed, measure the ceiling fuil size of room, 
and the walls up to ceiling; all in super, yards. 
(5) Deduct all openings 100 square feet and over; 
deduct materials and add labor (hollows) for net sizes 
of doors, windows, fireplaces, and other openings under 
100 feet super. (6) Where ceilings are paneled and 
coffered, or covered, girth round all portions that are 
lathed, keeping circular work separate. (7) Ceilings 
plastered between spars, etc., ta be measured across 
the spars and purlins, and even then kept separate, 
and described as such. (8) All work run with a mould 
to be measured lineal on the wall, and the girth given, 
as cornices, rustics, strings, architraves, soffits, quirks, 
etc.; count all miters with the girth of mould they 
belong to; count miters in paneled work. (9) All 
cornices, etc., lathed on brackets, to be kept separate, 
and described as such. (10) All cast work to be 
counted, except running enrichments. (11) Enriched 
members to be measured lineal, with girth. (12) 
Modeling of enrichments to be, if special, so stated, 
and the models to be the property of the designer. 
(13) Ceilings or walls covered with panels, formed by 
small moulds, to be measured super., with illustration 
or drawing, for “extra price over plain work”; larger 
paneling or special decorative features to be measured 
in detail. (14) Angies io pilasters, etc., if special.}'

formed, lineal and extra to plastering. (15) Door and 
window frames, bedding and pointing, to be counted, 
and state material to be used; also flushing to inside 
of frames after fixing, or behind casings, window 
backs, or other work to be given. (16) Making goods 
generally, and after plumber, gas-fitter, bell-hanger, 
etc., and chimney pieces, as in item, stating numbers. 
(17) Coloring and white-washing walls, etc., to be in 
super, yards, measuring over all openings under 100 
super, feet; if the work has to be pointed by the plas¬ 
terer, state so. (18) Painting to include stopping and 
knotting, and to be given in square yards. Priming 
to be separate, if on work painted before being fixed. 
Painting to be girthed round all exposed surfaces, 
except as below. (19) Balusters, if ordinary square, 
and girds, gates, and other metal work painted on both 
sides, with bards about 5 to G inches apart, to be meas¬ 
ured one surface only; if closer or slightly ornamental, 
1^ surfaces, and for very close or very ornamental 
work, 2 to 2-J- surfaces. (20) Windows to be meas¬ 
ured each surface over full size of opening for painting 
frame and sheets, or else the frames counted, and the 
sheets, if large squares, counted; but if in small squares 
(as old-fashioned crown glazing), then count the squares 
instead of the sheet. (21) Fancy or ornamental paint¬ 
ing to be measured in detail, with lengths of mouldings 
picked out, gilt, etc. All work in parti-colors to be 
kept separate from plain work. 

The cost of internal plastering largely depends on 
the number of coats; the second or floating coal 
involves four processes: running the screeds, filling- 
in, scouring with a hand-float, and “keying” the sur¬ 
face for the finishing coat. This coat costs about a 1c. 
more than the two coats and set. The third or finishing 

o 


AND CONTRACTOR’S GUIDE 


1 73 

coat also entails extra care and trouble. It involves 
laying, scouring, troweling, etc., and it requires ‘‘fine 
stuff,” consisting of pure lime, slaked, saturated till 
semi-fluid sand. If "gauged” with plaster of Paris in 
the proportion of three or four to one, the work dries 
quicker. This is also used for cornices and enrich¬ 
ments. Gauging with plaster costs about 8 cents each 
coat per yard extra, and therefore adds materially to 
the cost. The cements known as Keene’s and Parian 
have quick-setting properties, and give a hard, non- 
porous surface; they are laid in two coats, the first of 
cement and sand about ^ inch thick, and the finishing 
coat of neat cement. This kind of cement finish is 
used for angles and arrises, often on Portland cement 
grounds, also for mouldings, girder-casings, soffits, 
skirtings, and other decorative features. Compared 
with ordinary three-coat work, it costs about one and 
a half times as much. Some authorities give 80 cents 
per yard on brick, and others 30 on lath, including 
profits, and on Portland cement grounds. 

There are several patent fibrous plasters used on 
canvas, wood, and metal for ceilings and decorations, 
that are advertised. These vary in price about 28 to 
40 cents per yard. The estimator can obtain prices 
for any selected ceiling, wall filling, or decoration. 

In estimating items of plasterer’s work, care is neces¬ 
sary in ascertaining the quantities, and whether for 
"narrow widths,” or for circular work. If for narrow 
widths, an extra price is necessary, being for labor, 
which would come to about 8 cents per foot super, 
more, orlOcents if in plaster of Paris. The quantity 
should also determine the price; for large quantities 
the labor might be priced at 1 cent less. Keene’s fine 
quality cement takes a fine polish, and is used fot

internal decorations, panels, columns; on brick walls 
it should be applied on a rendering coat of Portland 
cement. Parian cement is used as a stucco, and is 
valuable on new-built walls, as it can be papered or 
painted very soon afterwards; 4 bushels of Parian to 4 
of clean washed sharp sand will cover 10 super, yards 
4 inch thick. The price is about the same as Keene’s 
cement. 

Rake out joints of old brick work to form “key” for 
plaster. 

This may be done in brick work for 3 to 5 cents per 
foot super., say 32 cents per yard, and the price 
depends much on the hardness of the mortar to be 
raked out. Raking out cement joint would be about <3 
cents per foot. 

Dubbing out 1 inch thick in tiles and cement to fill 
hollow in wall. This may be taken at from 9 to 13 
cents per foot super., according to the kind of wall, 
and whether a scaffold is necessary. 

Render, float, and finish in troweled stucco for paint. 
May be put down at 35 cents per yard on brick. Add 
for last coat finished troweled stucco for paint 13 cents 
per yard. Troweled stucco on lath would cost about 
9 cents per yard more.

EXTERNAL PLASTERING, PORTLAND CEMENT 

4 

Work in Portland cement is costly, as both the mate¬ 
rial and labor are heavy. Portland cement is mainly 
used in external work. Plastering will take 3 of sand 
to 1 of cement, except in reservoir or hydraulic work, 
when it is used nearly neat. It is generally sold by 
the bag of 100 pounds in place of the bushel, and its 
price is variable according to the quality and locality. 
Price lists should always be kept on hand. A gritted 
face is better for Portland cement finish than troweled 
work, as the latter is apt to blister. One bushel of 
cement and two of sand will cover yards j inch 
thick; one of cement to three of sand will cover about 
G^ yards of that thickness. So that practically we may 
say that one-sixth of a bushel of cement will cover one 
yard at the above thickness, worth about 15 cents; and 
three bushels of sand will cost GO cents, one-sixth of 
which will be also about 10 cents; add to which labor 
and profit, about 37 cents, making about 75 cents per 
yard. The items should clearly state whether the 
cement is “rendered” or “plain face,” or “render and 
float," or “troweled,” if on brick or lath. Mouldings, 
grooves, arrises are taken per foot run if not exceed¬ 
ing 12-inch girth; if above this, by foot super.; and all 
narrow widths, like panels, rustics, etc., should be 
stated, as the labor is greater.

Troweled rough stucco, with blue lias lime and good 
sand, and jointed. This is worth about 50 to 65 cents

tiling 

The cost of tiles and tiling can only be accurately 
ascertained by first getting price of tiles and cost of 
labor in laying them. These are laid in different 
ways; a door boarding, on cement, or on laths or bat¬ 
tens. The latter method is that generally employed. 
Tiles, in shape, are of two main classes; those which, 
like pantiles, interlock, and those which, like common 
plain tiles, are nearly flat, and are laid on the same 
principle as slates. In the former class innumerable 


AND CONTRACTOR’S GUIDE 


18; 


forms have been patented, but few of them get into 
general use, chiefly owing to difficulties of replacing 
when broken, and the trouble of fitting them to irregu¬ 
larly-shaped roofs. Plain or crown tiles are such as 
have a rectangular form and plane surface. A custom 
is supposed to regulate size, but they are generally 
10J inches long, GJ inches broad, and J inch thick, 
with two holes in them, through which oak pins are 
inserted to hang upon the laths. Sometimes cast-iron 
pegs are used instead, or frequently extra large flat¬ 
headed wrought nails, made of pure zinc or zinc and 
copper, which have the advantage of allowing a tile 
to be replaced from the inside of the roof by lifting up 
the others to place in the tile and drop in the nails in 
a few seconds. Sometimes, also, tiles have projecting 
nibs cast on in lieu of pegs, or they may be both holed 
and nibbed, so that if the nib is broken off, the tile 
may be nailed. In use, one tile laps over another, and 
that part which then appears uncovered is called the 
gauge of the tiling, likewise known as the fade or 
weather. Many tilers have a practice, when plain tiles 
are set in mortar, not to peg more than one hole in 
ten, or sometimes only every third or tenth course is 
nailed. This is bad, as with the decay of the mortar, 
the tile will slip down. For walls, battens, nailed or 
plugged to walls, are the best mode of fixing for ver¬ 
tical tile-hanging, the top of each tile being bedded in 
cement mortar, and the bottom double course bedded 
and pointed in cement on a tilting fillet. 

In dealing with tiles as a roof covering, the first 
thing to be sure of is that the tile selected is capable 
of excluding all damp, and will withstand the disin¬ 
tegrating influence of the weather. 

Pantiles are the commonest class of tiles, and are 


HODGSON’S ESTIMATOR 


188 

very cheap. They hold moisture a long time, and 
require extra strong roof timbers. They are best laid 
to a slope of about 24 degrees, and are mostly used for 
covering sheds, barns, and buildings which do not 
require a plastered ceiling. 

Plain tiles are smaller than pantiles, but being laid 
with more lap, are heavier per square. They can be 
laid to any slope from 25 to 60 degrees. 

Fancy roofing tiles are similar in many respects to 
plain tiles and are much used for external walls of 
half-timbered houses in some countries. 

Roofing tiles are subject to the same defects as terra¬ 
cotta, viz., if they are burnt thoroughly many of them 
twist and warp and will be found to be untrue, and if 
they are not burnt very hard they are liable to decay. 

A good tile should be well tempered, of good color, 
free from stones, carefully trimmed, should give forth 
a clear ringing sound, and take its weathering quickly. 

The characteristics of a good roofing tile are density, 
toughness, and incipient vitrification, the last named 
quality producing, to some extent, that pleasing tint 
familiarly known as “bloom,” one of the peculiarities 
of some makes of tiles. 

Among the best are Jersey tiles, the color of which 
varies from pale strawberry red to dark brindle (a deep 
reddish brown), or even to blue, through an almost 
infinite gradation of color, so that almost any color can 
be obtained. They get their weathering quickly, and 
are not porous. 

Sizes of tiles. Plain tiles, 10J inches by 6J inches 
by J inch, and weigh about 2^ pounds each, and 11 
inches by 7 inches by f inch, and weigh about 3 
pounds each. Pantiles are 134 inches by 1)J inches bv 
J inch, and weigh about 5J pounds each.

A square of roofing requires 800 plain Ties laid to a 
3-inch gauge, 700 tiles laid to a 3j-inch gauge, and 600 
tiles laid to a 4-inch gauge; and 180 pantiles laid to 
10-inch gauge, 164 pantiles laid to 11-inch gauge, and 
150 pantiles laid to 12-inch gauge. 

One square of plain tiles weighs about 15 cwt., and 
one square of pantiles about 8 cwt. 

Spruce tiling laths or battens are 1} inches by f inch 
to 2 inches by 1 inch, and oak tiling laths 1J by \ inch. 


100 plain tile laths 5 ft. long.1 bundle 

12 pantile laths, 10 ft. long.1 bundle 


One square of tiling requires 1 bundle of laths, 12 
hundred of nails, 1 peck of tile pins, and three hods of 
mortar. 

One square pantiling requires 1 bundle of laths and 
1 } hundred of nails. 

To ascertain the comparative merits of tiles, as to 
their weathering properties, there is no better test 
than the amount of water they will absorb. 

Most roofing tiles are slightly absorbent, except in 
the case of highly-fired brindled and blue tiles, and for 
this reason old tiles have, in a few isolated instances, 
attained to a higher market value than new tiles, as by 
age and atmospheric deposit they have acquired an 
artificial surface coating and lost the property of 
absorption, at least on their outer exposed surface. 

Tiles of a bright red, or an earthy red, color should 
be viewed with suspicion and avoided. They are 
invariably absorbent, and will not weather well. Tiles 
may be obtained of almost any color. 

Well-formed roofing tiles are straight in their width 
and hollow in their length, that the tails of each course 
may lie close and tight on the backs of the under 
course. 




HODGSON’S ESTIMATOR 


190 

Straight tiles will not clear themselves one over the 
other, and should therefore be rejected. Where point¬ 
ing is necessary, it is customary in good work to grind 
down some of the broken tiles, to mix with the Port¬ 
land cement as a substitute for sand, that the finished 
pointing may approximate in color to the general tone 
of the roof covering. 

The gauge of tiling is the distance from head to tail 
minus the lap divided by 2; thus a lOJ-inch tile laid to 
a 2J-inch lap will only expose 4 inches of its length to 
the view when the work is completed. 

FIXING 

Old-fashioned tiles have no nibs or stubs for hang¬ 
ing, and must therefore be kept in situ by means of two 
wooden pins or nails. 

When tiles are bedded in lime and hair mortar the 
tops only should be bedded, the mortar extending, 
say, not more than 3 inches below the head of the tile. 

When a roof is close-boarded (and sometimes felted) 
there is no need for bedding, though of course a cover¬ 
ing of bedded tiles is less liable to breakage when a 
man is climbing about a roof than would be one of 
unbedded tiles. 

In tiling roofs it is well to cover them with roof 
boarding and felting before laying the laths and tiles. 
This should always be done in good work. Occasion¬ 
ally architects are compelled, owing to the cost of 
work, to eliminate the felting, or covering with 2-ply 
paper, and lay the tiles on the boarding; but this 
practice is unwise, as experience shows, and the boards 
alone do not stop draughts. 

Secret gutters should only be used, in positions 


AND CONTRACTOR’S GUIDE 


191 

where they will always clear themselves, especially if 
tile dwelling be surrounded by trees. 

Tiles, and tile-and-a-half, should be worked against 
all secret and other gutters, where practicable, alter¬ 
nately on each course. 

Tiles overhanging secret gutters should not be 
bedded on the lead, nor should their edges be pointed, 
otherwise rain may be drawn into the roof. 

The lead welt should stand its own thickness above 
the backs of the battens, forming a tiit for the tiles, 
so as to throw the water away from their edge on to 
the main body of the roof. 

Ridge tiles should be of such a section as to admit 
of being pressed or made in one piece. Where an 
ornamental cresting is required, it should be made as a 
separate piece entirely detached from the ridge tile 
proper, the latter being made with a groove to receive 
the cresting. 

The cresting should not be stuck on the ridge tiles 
by means of semi-liquid clay while they are in the clay 
state. Such work is more or less defective and unsatis¬ 
factory in the end. 

Pantiles should be laid on laths and a good bed of 
hair plaster, in order to secure them to the roof. 

Tiles hung against vertical walls are treated precisely 
as are those on roofs. 

HIPS, VALLEYS, AND RIDGES 

In a tiled roof valley and hip tiles should be usea in 
preference to lead gutters, secret or otherwise, bed¬ 
ding the valley tiles at their heads to keep them in situ 
and steady while laying the plain tiles. 

Hip and valley tiles should be purpose made, with 
proper regard to their enclosed angle or pitch. 


192 


HODGSON’S ESTIMATOR 


Where a minor roof runs in at right angles to a 
greater or main roof, intersecting it at a point below 
the main ridge, it is desirable to use a piece of 4-pound 
lead dressed to the shape of the minor ridge and the 
slope of the main roof, and called a saddle-piece. 
This prevents the possibility of rain getting in at the 
junction of the roofs. 

The simplest form of ridge tile is that consisting of 
the two wings terminating in a roil at their angle of 
intersection. 

Another good form of ridge tile is that of a plain 
vertical blade rising from the angle of intersection of 
the wings, and with the square angle at each end of the 
blade cut off at an angle of 45 degrees, and which can 
be pressed in one piece by a simple operation. 

Ridge tiles should be well soaked before use, bedded 
in gauged lime-and-hair, and their vertical joints drawn 
up solid with cement, not simply pointed after they 
are fixed. 

When the roof is enclosed on the under side, it is 
customary to bed in lime-and-hair the eaves courses 
only, for the sake of steadiness in the fixing. 

As before stated, the cost of a tile roof will vary 
much according to locality and quality of materials 
used. The average cost per square, however, will be 
about $20.00 for the best tiling and about $15.00 for 
the more common kinds. While these figures are not 
correct, they may act as a sort of guide to the esti¬ 
mator when figuring on tile roofs. In all cases, how¬ 
ever, wherever possible, I advise that the local prices 
be obtained and that at least 15 per cent be added to 
these prices, unless the work is executed in a large city 
where prices are more constant than in country places; 
then only the usual percentage of profit be added. 


AND CONTRACTOR’S GUIDE 


193 


So little tiling is done in this country (more the 
pity) that expert tilers are scarce and wages high and 
varied, so that nothing can be given definitely regard¬ 
ing the cost of this work. 

In measuring for tiling, take the whole superficial 
area, and allow extra for eaves next parapets, 4 inches; 
dripping eaves, 6 inches; all hips and cuttings, 3 
inches, and for valleys, 12 inches. 

For pantiling, also take the whole superficial area, 
and at hips, take the length of the hip-rafter by 12 
inches for cutting and waste, to be added to the super¬ 
ficial area; take the run of hip and ridges, and of 
mortar or cement filleting, and the plain tile heading. 

Take in all cases the number of hip hooks and T 
nails to be painted in oil. 

Secure gauge of the tile, the quantity and descrip¬ 
tion of the laths and nails used; also if laid dry or 
pointed outside or inside with mortar or cement, and 
charge up accordingly; get exact cost of one square 
according to data given in the foregoing, and then 
find number of squares to be tiled, and multiply the 
number of squares by the cost of one square estimated 
upon. 


1 HE SLATER 

The great similarity which runs through the specifi¬ 
cations for slaters’ work, no matter by whom drawn, 
or for what class of work it is intended to apply them, 
is a mistake, as it often leads to bad results. The 
most suitable slate for the particular work in hand 
should be carefully selected. 

The architect should consider the pitch it is intended 
to give the roof, the length of span, and also whether 


i 9 4 HODGSON’S ESTIMATOR 

mitered or close-cut hips are to form any portion of the 
roof. 

If the hips are to be mitered, the angle should not be 
less than 45 degrees, otherwise very large slates must 
be used at the hip, which looks unsightly, and on no 
account should small pieces be allowed. 

Soakers should invariably be used where soft slates 
are laid, as flushing or bad work of any sort stains the 
slates and produces a bad effect. 

In exposed situations, where snow may be driven 
over the lap, it is better that the roof should be 
boarded and felted. If battens are used instead, ver¬ 
tical ones are less liable to cause a collections of snow at 
certain points, and apparent leakage when that occurs. 

When snow may slide off main roof on to any glass 
below, wire guards should be fixed along the eaves to 
check it. Open batten show-guttering should be pro¬ 
vided to all V and parapet gutters to allow snow-water 
to get away. 

Mitered hips and valleys with 4-pound lead soakers 
under slates make the neatest finish to slated roofs, 
and, if properly secured, the most satisfactory. In 
order to make a neat finish the roofs should be 45 
degrees pitch and the slates used in such cases should 
be small, say 16 x 8; the slater has then the choice of 
such sizes as 16 x 9, 10, and 12 to work up the hip 
with. It is impossible to obtain wider slates, and this 
often induces the slater to lay the slate lengthways to 
save the introduction of small pieces; the sides of the 
roofs forming the miter should be of the same pitch. 

If additional precaution is deemed necessary, small 
rolls may be screwed down to the hip rafter, over the 
mitering; this is rather unsightly and not recom¬ 
mended if soakers are used. 


AND CONTRACTOR’S GUIDE 


195 


Slates should be nailed with copper nails, which are 
practically imperishable. The life of a zinc nail rarely 
exceeds twenty years, and iron still less. 

In soft and rag slating the nails should be very 
stout, and the length 2 inches, If inches, and IT inches; 
few of the latter, if any, should be used, say on the 
last three or four courses only; the strength should be 
1)0, 110, and 130 to the pound respectively. 

In regular-sized work such stout nails are inad¬ 
visable, as the heads are large and will not recess as 
readily into the slate, and the top of the head must be 
flush with the surface of the slate, or anything press¬ 
ing on that particular part will damage the slate above; 
14-inch and If inch nails are recommended, 180 and 
250 to the pound respectively. 

Gauge. —The gauge of slating is the part left ex¬ 
posed, viz., deduct the lap from the total length of 
slate and half the remainder, thus, 

20 - 3 = 17 = 84- 

Lap for soft and rag slating should never be less 
than 3 inches. For regular-sized slating, 4 inches to 
2f inches, according to pitch of roof. 

Repairs to roofs should be done by an experienced 
slater and straps prohibited; the lead or zinc strap is a 
ready way, but raises the tail of the slate up, and is 
turned back bv snow slipping down and slate slips 
with it. 

Slating on unplaned boards is preferable to that on 
battens, because it is more waterproof and prevents t u ~ 
ingress of driving snow. The cost of good quality 
J-inch rough board is about $2.00 per square as com¬ 
pared with 75 cents for 2x4 inch slate battens, and the 
labor of laying and quantity of nails equal in each case. 

In superior work heavy felt (inodorous or otherwise) 


196 


HODGSON’S ESTIMATOR 


is inserted between the covering boards, and the slates 
.or battens may be added above the felt to render the 
building more proof against sun heat. 

Bedding and pointing on under side is not recom¬ 
mended unless the roofs are well ventilated; the heat 
of the house will condense on the under side of slate 
and quickly rot the wood work, and, in course of time, 
the slate also. Experience shows that a rough slate 
will keep out driving rain better than a smooth one, if 
well laid; the reason for this is that there is a con¬ 
siderable quantity of air between the surface of rough 
slate and practically no suction; also the thick edge of 
the slate breaks up the force of the wind on the sur¬ 
face of the slates. 

In church roofs, where the pitch is very sharp, small 
slates are recommended, from 14 x 8 to 18 x 9, accord¬ 
ing to pitch; as the pitch decreases the slate should be 
wider. 

For roofs of warehouses, where much depends on 
the work being perfectly water-tight, “tin” slates are 
recommended; they are about f inch thick, and are 
large and laid in diminishing courses, the gauge being 
about 15 inches at the eaves and 10 inches at the ridge. 

These slates are scarce, and architects should insist 
on the order being placed when the contract is signed, 
to ensure delivery in time. 

If it is thought advisable to use the above-mentioned 
slates, sizes such as 10 x 12, 18 x 12, 20 x 22, 22 x 12, 
and 24 x 12 are suggested, the size varying according 
to pitch. 

For curb and mansard roofs, slates larger than 16 x 9 
should never be used, the whole weight being thrown 
on the nail in such cases. The appearance of small 
slates is also far hetter on such roofs. 


AND CONTRACTOR’S GUIDE 


197 


With span of 25 feet to 40 feet, which entail a deep 
rafter and flat pitch, it is a wise precaution to vary the 
lap, giving extra at eaves and for a third of the way up 
the slope; in such roofs the slates should not be less 
than 11 inches wide, the extra width being a safeguard 
against side leakage through the nail holes 

Merchants are only able to obtain a proportion of 
sizes yielded by the rock, consequently it is some¬ 
times impossible to fulfill the general specification of 
20 x 10 Countess slate, as the quarries will not sacrifice 
the rock to make the full demand of 20 x 10 if the 
block will make 20 x 12; if 20 x 10 were insisted on, in 
that case it would entail an extra cost of about $3.50 
per square over other sizes. 

Actual size has little to do with the quality of the 
work, the lap is the principal factor, and the result in 
16 x 10 or 20 x 10 is exactly the same. The best all¬ 
round size is probably 16 x 10. 

Single samples are very unsatisfactory means of 
judging of the quality of the bulk; at least six 
should be demanded, showing medium and thinnest. 
Where possible, the inspection of the bulk should be 
made. 

A good slate is hard and tough, will give a sharp 
metallic ring when struck with the knuckles, does not 
split under the slater’s ax, is easily holed without 
fracture, not tender or friable at the edges, and should 
contain no white iron pyrites (marcasite). 

A bad slate feels smooth and greasy to the touch, 
absorbs moisture if stood in water, splits while being 
holed or trimmed at the head, breaks when pressed 
upon, emits a clayey odor when breathed upon, and is 
liable to premature decay. 

Slate, ridge roils and wings should be fastened with 


198 


HODGSON’S ESTIMATOR 


brass or copper screws, and bedded and pointed in lead 
cement, one-third lead and two-thirds best oil putty. 
Iron screws should not be permitted, they oxidize and 
burst the rolls. If wings more than ^ inch thick are 
used the upper edges must be beveled. 

Half or checker slating is sometimes employed for 
farm buildings or where special ventilation or cheap 
covering is required. The saving by this method is in 
the quantity of slates and nails used; the battens or 
boards remaining the same. In place of the slates 
being butted close to one another,'they are spaced 
laterally in such a manner as to just cover the joint 
between the slates in the course below. This slating, 
known also as open slating, is well adapted for use in 
farm buildings, covered yards, etc., as by its construc¬ 
tion it affords a certain amount of ventilation. 

In laying slate there is always an element of risk of 
breakage that must be accounted for, and, as all roofs 
must be left in good order and perfectly water-tight, 
an allowance of about 25 cents per square must be 
made above all other provisions. It is very necessary 
to go carefully over the slating and see that the slater 
who does the work makes good any deficient or broken 
slates before he leaves it; and beyond that there is the 
risk of breakages from oth^r workmen, for some men 
must go on the roof after, all hough as much as pos¬ 
sible this should be avoided. 

Cutting round small ventilators, V-shaped on plain, 
and 12 inches by 12 inches. — If the ventilator itself 
measures 12 by 12, the flashing round it will, of course, 
exceed the dimension and the slate will not run close 
up; giving another foot run of cutting, the slate would 
have to be tilted against the ventilator to throw the 
water off, or a secret gutter formed. The eaves cut-

at 6 inches of it.

No more beautiful slate is quarried in the world than 
the Brownville. It is very uniform in thickness and 
of smooth surface, and when laid on the roof presents 
a surface equal to polished steel. For costly private 
residences, churches, and public edifices, it has no 
superior.

To obtain the correct measurement of a surface of a 
slate when laid, and the number of squares on any par¬ 
ticular surface, we simply subtract the lap from the 
length of the slate and half of the remainder will give 
the length of the surface exposed, which, when multi¬ 
plied by the width of slate, gives the surface sought; 
so that to obtain the exact number of slates of any 
description required to cover any given surface is quite 
a simple matter. Further on I will give a rule for 
finding the number of slates required for covering any 
given area.

There are certain rules that are generally recognized 
by estimators and builders for the measurement of 
roofs, whether of slate, shingles or other materials, 
and may be given as follows: 

For plain roofs, measure the length of the roof and 
multiply by the length of the rafter. 

For roofs with hips, valleys, gables, dormers, etc., 
measure each section through the center and multiply 
by length of rafter, and in addition to the actual sur¬ 
face of the roof, measure the 
length of all hips and valleys, 
by one foot wide. No deduc¬ 
tion is made for dormer win¬ 
dows, skylights, chimneys, etc., 
unless they measure more than 
4 feet square. If more than 4 
feet square, and less than 8 feet 
square, deduct one-half; if more 
than eight feet square, deduct 
the whole. Ifhipsare mitered, 
charge extra. Ridge rolls, flash¬ 
ings, valleys, etc., are charged 
extra. 

The names given to ornamen¬

HODGSON’S ESTIMATOR 


$5.00 per day of nine hours, and he is supposed to lay 
about squares, providing everything is handy for 
him. This wage, however, may be, and is, only given 
in a few localities. In some towns it is less, and in 
some cities it is more; so that the estimator should, 
wnenever possible, obtain local prices both for labor 
and material; then he cannot well make many errors in 
his estimate if he is at all careful. 

The following hints regarding preparing estimates 
may not be out of place, and I give them even if I risk 
being accused of repetition, as I have given nearly the 
same advice in previous pages; but it cannot be given 
too often to the young and inexperienced estimator, 
for the omission of a single item may result in grievous 
loss. 

The first thing to do, before commencing to make an 
estimate of the cost of a job of work, is to see to it that 
the drawings and specifications be carefully studied 
and remarks made for future guidance or reference. 

Excavator and Bricklayer. —Take the dimensions for 
the excavations wholly from plans and sections, then 
refer to the specification and add whatever does not 
appear on the drawings. 

Take brick work as above directed. 

The chimney bars may be taken with the dimen¬ 
sions of the breasts; refer to specifications for descrip¬ 
tion. 

The centering and spring pieces may be taken with 
arches. 

The wood bricks and springing pieces may be taken 
with brick arches. 

Take dimensions by the foot run of the making good 
and restorings of all stone sills, after mason, etc. 


AND CONTRACTOR'S GUIDE 


205 


Slater. —Take from the plan of roof and section, 
then refer to specification and clear all off. 

In the bill provide for leaving all slating perfect at 
completion of the work. 

Carpenter. —Take from plans and sections, referring 
to specification. Take ah iron attached to timbers. 
Find the quantity of boarding, or battening, to roof, 
with the slating, deducting eaves, cuttings, etc., from 
the latter; if much discrepancy, there must be an 
error. 

Plumber. —Take everything from specification, refer¬ 
ring to drawings only for lengths. Be careful in allow¬ 
ing all turnings up under slating and against walls, 
round rolls, flashing, etc. (refer to the quantity of 
boarding to flats, etc., as a check.) 

Mason. —Take from specification, referring to the 
drawings only for dimensions. Attend to the cube 
quantities, scantling lengths, etc., also to the method 
pointed out for taking labor. 

Joiner and Hardware. —Peruse specification, referring 
to drawings only for dimensions. Take hardware 
from floor to floor. Provide for casing stairs, and 
covering handrail to prevent any injury during the 
progress of the work, and for projecting masonry in 
like manner. 

Provide for attending plumbers to sinks, cisterns, 
W. C., etc., stating how many of each. 

Plasterer, Internally. —Look carefully to specification, 
particularly as to enrichments, referring to drawing 
for dimensions. Whitening and coloring is taken from 
plastering, but appears separately. 


206 


HODGSON’S ESTIMATOR 


Provide for making good round mantels after 
mason. 

Glazier.—Can find all in specification, referring to 
drawings for any size. Check quantity of glass by the 
sashes, allowing for wood. Provide for leaving same 
clean and sound. 

Painter.—All taken from specification. 

All wood work painted may be collected from the 
joiner; one-seventh for edges; when both sides are 
painted, double dimension. Painting for plastered 
walls, from plasterer. 

Paper-Hanger.—May be taken from plasterer. 

Summary of trades in order. Conditions of contract 
to be taken from specification, and furnished in the 
memorandum sheet. 

Fees.—Government, municipal, sewer, and architect’s 
fees to be attached at end. 

At the head of each trade give fair description from 
specification of quality of materials, etc. 

Lastly.—Generally review the whole of the drawings 
and specifications, that nothing may be omitted or mis¬ 
represented. 

RULES, TABLES, NOTES, DATA, AND POINTERS USEFUL 

TO THE ESTIMATOR 

The following tables, data, etc., have been specially 
selected for the use of the estimator, and will be found 
useful for reference and for making hurried approxi¬ 
mate estimates of work in detail or in bulk. The 
'terns are carefullv indexed, so that any particular one

of them may be found without much loss of time; a 
matter of considerable importance to the busy man, 
It would extend the limits of this book too far beyond 
the size intended to insert tables of scantling measure¬ 
ment, wages, extended tables of diameters, circum¬ 
ferences and areas of circles and similar matter, which 
after all are not of much actual service to the esti¬ 
mator, but which are usually published in works of this 
kind.

Brick work is generally measured by 1,000 bricks 
laid in the wall. In consequence of variations in size 
of bricks, no rule for volume of laid brick can be 
exact. The following scale is, however, a fair 
average: 


7 com pressed bricks to a super, foot 4-in. wall. 
14 compressed bricks to a super, foot 9-in wall. 
21 compressed bricks to a super, foot 13-in. wall. 
28 con.pressed bricks to a super, foot 18-in. wall. 
35 compressed bricks to a super, foot 22-in. walk 

























































AND CONTRACTOR’S GUIDE

Corners are not measured twice, as in stone work. 
Openings over 2 feet square are deducted. Arches 
are counted from the spring. Fancy work counted 1^ 
oricks for 1. Pillars are measured on their face only. 

A cubic yard of mortar requires 1 cubic yard of sand 
and 9 bushels of lime, and will fill 30 hods. 

One thousand bricks closely stacked occupy about 
56 cubic feet. 

One thousand old bricks, cleaned and loosely 
stacked, occupy about 72 cubic feet. 

One superficial foot of gauged arches requires 10 
bricks. 

Pavements, according to size of bricks, take 38 brick 
on flat and 60 brick on edge per square vard. on an 
average. 

Five courses of brick will lay 1 foot in height on a 
chimney; 6 bricks in a course will make a flue 4 inches 
wide and 12 inches long, and 8 bricks in a course will 
make a flue 8 inches wide and 16 inches long.

MASONRY 

Stone masonry is measured by two systems, Quarry- 
man’s and Mason's Measurements. 

By the Quarryman’s Measurements the actual con¬ 
tents are measured; that is, all openings are taken out 
and all corners are measured single. 

By Mason s Measurements, corners and piers arr 
doubled, and no allowance made for openings less 
than 3x5 feet and only half the amount of openings 
larger than 3x5 feet. 

Range work and cut work is measured superficially 
and in addition to wall measurement. 

An average of six bushels of sand and cement per 
perch of Rubble Masonry. 

Stone walls are measured by the perch (24f cubic 
feet). Openings less than 3 feet wide are counted 
solid; over 3 feet deducted, but 18 inches are added to 
the running measure for each jamb built. 

Arches are counted solid from their spring. Corners 
of buildings are measured twice. Pillars less than 3 
feet are counted on 3 sides as lineal, multiplied by 
fourth side and depth. 











AND CONTRACTOR’S GUIDE 


211 


It is customary to measure all foundation and dimen¬ 
sion stone by the cubic foot. Water tables and base 
courses by lineal feet. All sills and lintels or ashlar 
by superficial feet, and no wall less than 18 inches 
thick. 

The height of brick or stone piers should not exceed 
12 times their thickness at the base. 

Masonry is usually measured by the perch (contain¬ 
ing 24.75 cubic feet), but in practice 25 cubic feet are 
considered a perch of masonry. 

Concreting is usually measured by the cubic yard 
(27 cubic feet). 

A cord of stone, 3 busheis of lime, and a cubic yard 
of sand, will lay 100 cubic feet of wall. 

Cement, 1 bushel, and sand, 2 bushels, will cover 3£ 
square yards 1 inch thick; 4^ square yards f inch thick, 
and Gf square yards 4 inch thick; 1 bushel of cement 
and 1 of sand will cover 2£ square yards 1 inch thick, 
3 square yards f inch thick, and 44 square yards 2 inch 
thick.

ROOFS GENERALLY 

SHINGLING 

To find the number of shingles required to cover 100 
square feet deduct 3 inches from the length, divide the 
remainder by 3, the result will be the exposed length 
of a shingle; multiplying this by the average width 
of a shingle, the product will be the exposed area. 
Dividing 14,400, the number of square inches in a 
square, by the exposed area of a shingle will give the 
number required to cover 100 square feet of roof. 

In estimating the number of shingles required, an 
allowance should always be made for waste. 

Estimates on cost of shingle roofs are usually given 
per 1,000 shingles.

SLATING 

A square of slate or slating is 100 superficial feet. 

In measuring, the width of eaves is allowed at the 
widest part. Hips, valleys and cuti'ngs are to be 
measured lineal, and 6 inches extra is allowed. 

The thickness of slatesTequired is from 3-16 to 5-16 
of an inch, and their weight varies when lapped from 
4,0 to Of pounds per square foot.

The “laps” of slates vary from 2 to 4 inches, the 
standard assumed to be 3 inches. 

TO COMPUTE THE NUMBER OF SLATES OF A GIVEN SIZE 

REQUIRED PER SQUARE 

Subtract 3 inches from the length of the slate, 
multiply the remainder by the width and divide by 2. 
Divide 14,400 by the number so found and the result 
will be the number of slates required.

SNOW AND WIND LOADS 

Data in regard to snow and wind loads are neces¬ 
sary in connection with the design of roof trusses. 

Snow Load. —When the slope of a roof is over 12 
inches rise per foot of horizontal run, a snow and 
accidental load of 8 pounds per square foot is ample. 
When the slope is under 12 inches rise per foot of 
run, a snow and accidental load of 12 pounds per 
square foot should be used. The snow load acts ver¬ 
tically, and therefore should be added to the dead load 
in designing roof trusses. The snow load may be 
neglected when a high wind pressure has been consid¬ 
ered, as a great wind storm would very likely remove 
ail the snow from the roof. 

Wind Load. —The wind is considered as blowing in a 
horizontal direction, but the resulting pressure upon 
the roof is always taken normal (at right angles) to the 
slope. The wind pressure against a vertical plane 
depends on the velocity of the wind, and, as ascer¬ 
tained by the United States Signal Service at Mount 
Washington, N. H., is as follows: 

Velocity Pressure 

(Mi. per Hr.) (Lb. per Sq. Ft.) 

10.0.4.Fresh breeze. 

20. 1.6.Stiff breeze. 

30. 3.6.Strong wind. 

40. 6.4.High wind. 

50.10.0.Storm. 

60.14.4.Violent storm. 

80.25.6.Hurricane. 

100.40.0.Violent hurricane. 
























22 0 


HODGSON’S ESTIMATOR 


The wind pressure upon a cylindrical surface is one- 
half that upon a flat surface of the same height and 
width. 

Since the wind is considered as traveling in a hori¬ 
zontal direction, it is evident that the more nearly ver¬ 
tical the slope of the roof, the greater will be the 
pressure, and the more nearly horizontal the slope, 
the less will be the pressure. The following table 
gives the pressure exerted upon roofs of different 
slopes, by a wind pressure of 40 pounds per square 
foot on a vertical plane, which is equivalent in inten¬ 
sity to a violent hurricane.

In addition to wind and snow loads upon roofs, the 
weight of the principals or roof trusses, including the 
other features of the construction, should be figured in 
the estimate. For light roofs having a span of not 
over 50 feet, and not required to support any ceiling, 
the weight of the steel construction may be taken at 5 
pounds per square foot; for greater spans, I pound per 
square foot should be added for each 10 feet increase 
in the span. 












AND CONTRACTOR’S GUIDE 


221 


COMPARATIVE COST OF ROOFS 

It often happens that an estimator is asked as to the 
difference in the cost of roofs, and on his answer the 
construction of the work may depend; therefore it is 
necessary that he should be able to give his answer with 
some degree of intelligence and exactness; and the 
following, to some extent, will enable him to do this. 

For instance, take a “span roof,” by which we mean 
one having two sides inclining to a ridge, and let the 
length of the rafter be 16 feet, and that of the roof 
from edge to edge be 14 feet. 

Then it contains on each side a trifle over 7 squares 
of 100 superficial feet each. 

If the roof is to be slated or tinned it will require 
the sheathing to be laid close, and with what is called 
“match mill-planed timber,” which is provided with 
tongue and groove, and need not, as the name implies, 
be mill-planed, although it usually is. 

We next come to consider the cost of sheathing, 
nails, and labor required in putting it on, which, 
approximately, is as follows: 

PREPARING FOR SLATE OR TIN ROOF 

7 squares of roofing require 700 feet of sheathing 

at $20 per M.$14.00 

Labor required in putting same on, at 50 cents 

per square . 3.50 

Nails for fastening sheathing boards. 1.25 

Total cost .$18.75 

SLATE ROOF 

We find the cost of the slate roof to wit: 

For preparing for roof.$20.00 

For 7 squares of slating, including labor, material, 

etc., at $15 per square.105.00 


Total cost 


$125.00 











222 


HODGSON’S ESTIMATOR 


Thus it will be seen that the total cost of 1 squares 
of slating aggregates a cost of $125.00, or $17.85 per 
square. 

TIN ROOF 

Since the work of preparing for the tin roof is the 
same as for slate, we add to it the cost for tin and 
painting as follows: 

For preparing for roof.$18.00 

For 7 squares of tin work at 75 cents per square, 

including material and labor. 60.00 

For 78 yards of paint, 2-coat work, at 20 cents 

per yard. 15.60 

4 

Total cost.$93.60 

At these figures we find that 7 squares of tin roofing 
will cost $98.60, or a trifle over $14.00 per square. 

SHINGLE ROOF 

In estimating the amount of sheathing required for 
a shingle roof, we bear in mind the fact that it will not 
be necessary to lay boards close together; but strips 3 
inches wide can be used, and if so, it will require about 
one-half of the amount it does when laid close, as for 
the slate or tin roof. Hence the following is the approxi¬ 


mate estimate of cost. 

300 feet of sheathing at $15.00 per M.$ 4.50 

Labor required in putting same on. 1.50 

Nails for sheathing, etc.. .60 

7,000 shingles, nails and labor at $8 per square. .. 56.00 

Total cost.$62.60 ' 


Thus the cost of 7 squares of shingling will aggregate 
$62.60, or a trifle over $8.15 per square. 












AND CONTRACTOR'S GUIDE 


223 


COMPOSITION ROOF 

Now suppose that the slope of the roof permitted 
the surface to be covered with gravel or composition 
roofing, then the sheathing need not be laid as care¬ 
fully as for tin or slate, and an inferior quality of lum¬ 
ber can be used; the only requirements being that the 
surface must be level and smooth. 

In such a case the estimate of cost would be as 
follows: 


700 feet of sheathing at $20.00 per M. $14.00 

Putting on same at 40 cents per square. 3.4.1 

Nails for sheathing, etc.1.25 

7 squares roofing material, etc.,.$5 per square.... 35.00 


Total cost.$53.60 


Making the cost of 7 squares amount to $53.60, or a 
trifle over $7.63 per square. 

*Slate on iron purlins.$2.00 to $7.00 per sq. 

Metal tile, tin. 8.50 to 9.75 per sq.

THE METRIC SYSTEM 

The metric system is based on the meter, which, 
according to the United States Coast and Geodetic 
Survey Report of 1884, is equal to 39.370432 inches. 
The value commonly used is 39.37 inches, and is 
authorized by the United States government. The 
meter is defined as one ten-millionth the distance 
from the pole to the equator, measured on a meridian 
passing near Paris. 

There are three principal units: the meter, the liter 
(pronounced lee-ter), and the gram, the units of length, 
capacity and weight, respectively. Multiples of these 
units are obtained by prefixing to the names of the 
principal units the Greek words Deca (10), hecto (100), 
and kilo (1,000); the submultiples, or divisions, are 



















228 


HODGSON’S ESTIMATOR 


obtained by prefixing the Latin words Deci (1/10), 
centi (1/100), and milli (1/1000). These prefixes form 
the key to the entire system. In the following tables 
the abbreviations of the principal units of these sub¬ 
multiples begin with a small letter, while those of 
the multiples begin with a capital letter; they should 
always be written as here printed.

HOW TO FIGURE PLASTERING 

Multiply the distance around the four sides of the 
room in feet by the height of the room in feet. Mul¬ 
tiply the product by the price per square yard and 
divide this product by 0, because there are 9 square 
feet in a square yard. For the ceiling, multiply the 
length of the room by the width of the room in feet 
and then by the price per square yard, and divide by 9 
as before. Add these two results and you have the 
entire cost of plastering the room. 

To every barrel of lime estimate about f of a cubic 
yard of good sand for plastering. 

One-third of a barrel of stucco will hard finish 100 
square yards of plastering. 

Six bushels of lime, 40 cubic feet of sand and 1^ 
bushels of hair will plaster 100 square yards with two 
coats of mortar. 

In plastering, no deductions are made for openings, 
because it is considered that the extra work in finish¬ 
ing around them balances the material saved.

ESTIMATING FRAME OR BALLOON BUILDINGS 

In estimating the cost of labor necessary to convert 
rough lumber into available building material, the esti¬ 
mator should divide the labor as follows: 


























AND CONTRACTORS GUIDE 


233 


First, ascertain the cost of framing sills, joist, studs, 
rafters, and like dimension stuff on the ground ready 
to go into the building. 

Second, estimate the cost of placing it on the build¬ 
ing, or into the work. Siding, roof boards, sheathing, 
furring and flooring requires no primary labor to pre¬ 
pare it for the building; and, therefore, this class of 
material calls for the price of labor only to put it on 
the building. 

The simplest method to estimate the labor of fram¬ 
ing dimension or piece stuff, as scantling of all kinds, 
is by the thousand feet. A general rule adopted by me 
after a long experience and considerable investigation, 
is to add the entire bill of dimension stuff together, 
and price it for medium work at $5.00 per thousand for 
the labor of framing on the ground, and $6.00 per thou¬ 
sand for labor of working it into the building. We base 
bur rule on the following demonstrations: 

Two good carpenters will lay out and frame 50 pieces 
of 2x10 joists, 16 feet long, in a day of 9 hours, or 
about 1,350 feet; or they will frame 100 pieces of 2x6 
studding 12 feet long, in a day, or 1,200 feet; or they 
will frame 70 pieces of 2x6, 16 feet long, for rafters, 
in a day, or 1,120 feet; or they will frame Id pieces 
of 8x8 sills, 16 feet long, or 1,190 feet. Calling car¬ 
penters’ wages at $5.00 per day, we find that the 
framing of 


Joist, 1,350 feet, cost.$11.00 

Studding, 1,200 feet, cost. 11.00 

Rafters, 1,120 feet, cost. 11.00 

Sills, 1,190 feet, cost. 11.00 


Averaging the above, we find the price to be about 
$6.00 per 1,000 feet. 






234 


HODGSON’S ESTIMATOR 


For siding, roof boards, sheathing and flooring, the 
price may be fixed as on the following basis: 

Two good carpenters will put on 800 feet of lap siding 
in a day, or 1,600 feet of roof boards per day; staging 
not included. Calling wages at $5.00 per day, we find 
that to put on 

Siding, costs $8.00 per 1,000 feet. 

Roof boards, cost $9.00 per 1,000 feet. 

Sheathing, costs $5.00 per 1,000 feet. 

One good man will lay 900 feet of 1x6 matched 
flooring in a day, or 700 feet of 1x4 matched'flooring 
in a day. At the same rate of wages the 1x6 floor 
will cost $6.00 per 1,000 feet to lay, and the 1x4 floor 
will cost $6.00 per 1,000 feet to lay. 

A good man will carry up and lay on a roof from 
1,600 to 2,400 shingles per day, which estimated at the 
same rate of wages and averaged, is $2.00 per 1,000. 

Two men will put on 2,000 feet of felt paper per day, 
which being reduced from the same rate of wages, 
makes it cost 35 cents per square of 100 feet. 

Two men will lay 500 to 600 feet of outside beaded 
ceiling work per day, or say $13.00 per 1,000 feet. 

A man will put down 200 feet of plain base per day, 
or 100 feet of moulded base. 

A man will fit and nail 400 pieces of bridging per 
day, or 1 cent each. 

Returning again to dimension stuff, as joists, studs, 
rafters, sills, etc., we find that two good men will place 
50 pieces of 2x10 joists, 16 feet long, in a day, or 150 
pieces of 2x6 studs, 12 feet long, in a day, or 100 
pieces 2x6 rafters, 16 feet long, in a day, or 20 pieces of 
8x8 sills in a day. 

For the labor necessary to place material on a building. 


AND CONTRACTOR’S GUIDE 


235 

some builders estimate labor by the square, as follows: 
Wages $5.00 per day. 

Drop siding, $1.00 a square. 

Lap siding, 90 cents a square. 

Sheathing, 30 cents a square. 

Surface boards, 35 cents a square. 

Roof boards, plain, 35 cents a square. 

Hip roofs, $1.00 a square. 

Steep roofs, $1.05 a square. 

Shingles, $1.20 to $1.50 a square. 

Floor pine, 1x6, 45 cents to $1.00 a square. 

Floor pine, 1x4, 45 cents to $1.00 a square. 

Floor pine, 1x3, $1.00 to $1.75 a square. 

Outside wall ceiling, $1.25 a square. 

Soffit ceiling, $1.25 a square. 

Wainscoting, from $3.00 to $4.00 a square. 

Cleaning off pine floor, from 25 cents to $1.10 a square. 

Tin work, valleys 14 inches wide, a man will lay 
from 1 to If square feet of valleys per day. 

In closing this series of tables upon one of the most 
vital subjects connected with the building profession, 
I desire to call attention to the fact that the manner 
of taking out quantities in the United States is some¬ 
what different from that of Europe, and especially 
that of England, where the rules and methods con¬ 
nected with this particular branch of building are 
settled and well defined. In the embryonic state of 
our building practice, we have no universal or general 
methods of drawing off quantities, excepting what has 
come out of necessty. 

The time will doubtless come when we shall have a 
universal method that shall not only be thoroughly 
established by practice, but indorsed by the various 
building trades and architectural associations through¬ 
out the entire country, so that a mechanic, having 


236 


HODGSON’S ESTIMATOR 


become conversant with the rules and methods of New 
York, will not be called upon to study and make him¬ 
self familiar with the rules and methods practiced in 
St. Louis or Chicago. 

Large cities, by virtue of the facility for organization 
in the several branches of the building trades, are 
enabled to establish rules of measurement that govern 
their individual membership, but cannot control the 
conduct of other trades; hence, upon examination, it 
will be found that the rules of measurement for 
masonry in New York City vary from the rules in use 
in Cincinnati, Chicago and other large cities. 

I am aware that the primary rules of mensura¬ 
tion, that is, the method of measuring any given sur¬ 
face or body, is governed by certain algebraic and 
mathematical calculations, which may be used by any 
one when he has mastered the proper method of 
procedure, and it is to illustrate and make plain this 
method that this book is written not only from a prac¬ 
tical standpoint but from an American builder’s view 
of the methods best adapted to the business interests 
of the builder. 

Another somewhat different method than the fore¬ 
going is given herewith; it is taken from a trade jour¬ 
nal of reliability, and possesses considerable merit. 
The system is all right, but the prices given are not to 
be followed, as they are much too low, not being 
within 40 to 50 per cent as high as current prices in 
the larger cities. This is especially arranged for bal- 
.oon frame. 

The first is an analysis of cost of four squares outside 
walls. For convenience, suppose a space 20 x 20 feet 
as a basis, resulting in 400 square feet, or 4 squares. 
The studding employed is 2 x 4 inch, sized on one

side and one edge. The studding is placed 16 inches 
from centers and covered with dressed and matched 
stuff. Building paper is next laid on, and then first 
or second clear siding is used. Plates are included in 
the cost and are put on double thickness.

painters’ measurements 

In England the custom is to employ a clerk quick at 
figures, whose duty it is to take off, from tne plans 
and specifications, an accurate list of all the materials 
and labor required in the performance of the work, 
setting down in each case the number of yards or feet, 
as the case may be, of each item. In the case of 
painting, the figures obtained for the carpenter and 
joiner prove of service also for the work to be done by 
the painter. The following is a table that is intended 
to indicate the method of measurement of painters’ 
work, and also the order in which the various items 
may be taken. A similar table added to, or changed, 
as might be necessary to suit American methods of 
construction, would be very useful to have on hand 
when getting out estimates, as it would insure nothing 
being left out. The table which follows accurately 
indicates the English practice.

TO FIND THE NUMBER OF SINGLE ROLLS OF PAPER 
NEEDED FOR ANY GIVEN ROOM. 

To find the number of single rolls required for a 
wall, multiply the distance around the room by the 
height, taking out 20 square feet for each opening, 
and divide by 30. To find the number of rolls for the 
ceiling, multiply the length by the width and divide 
by 30. The number of yards of border required can 
easily be measured. 

For example, room 12 x 14, 10 feet high, two doors 
and three windows:

The pri-ce of border is for a single strip, the width of 
the border and one yard long. 

The price of the paper is for a single roll, one-haif 
yard wide and eight yards long. Allowing for all 
waste, this will cover 30 square feet.

HODGSON’S ESTIMATOR 


CONCLUSION 

In conclusion I would suggest the following simple 
method of keeping a record of cubic contents and 
cost, and would say that the information an architect 
has of this kind from his own buildings is the best for 
him, as it is probable that no other architect is quite 
similar in his style of work and finish. 

A book or a number of sheets of paper should be 
ruled in suitable widths for the following columns: 1st, 
date (year); 2d, name of building (for owner); 3d, 
where erected; 4th, short description; 5th, cubical 
contents in feet; Gth, cost of building; 7th, cost per 
cubic foot; 8th, remarks. The kinds *of buildings 
should be classified so that prices of one class may be 
seen and compared at a glance in one column. An 
example is here shown.

Where

Cost 
$ c. 

Cts. 
per

Remarks 











































In computing the cubical contents the rule most 
commonly used is to measure the building as a whole 
or in parts from the bottom of the footings to a point 
halfway up the slope of roof, this being done in parts 
where there are different heights of roofs, towers, etc. 
In measuring brick or stone buildings, light wooden 
porticos or verandas are usually omitted. There 
should be a uniform system of omitting or including 
such items as heating, mantels, grates and tiles, elec¬ 
tric wiring, or of noting two rates, one omitting and 
the other including these. 



















AND CONTRACTOR’S GUIDE- 


247 


Indeed, an exact record of the cost of all buildings 
the contractor may erect, should be kept, and any¬ 
thing peculiar or uncommon or unusual should be 
noted, that in the future the knowledge obtained in 
this manner may be put to good purpose. 

In this work I have described several schemes for 
estimating and have given my views as to their 
respective merits, and the more I have examined into 
the question of estimating, the more I am confirmed in 
the views expressed in the first pages of the work, 
namely, that “no exact methods of estimating can be 
given,” and that the best and most reliable way is to 
estimate in detail. All other methods have certain 
good points, but, as a rule, they lack reliability, a 
quality the young contractor does not want to be up 
against; so it is better he should follow the safer, if 
more laborious way of figuring on every item going 
into the building he is about to tender for. A cele¬ 
brated artist once explained that his success as a 
painter arose from his following the rule, “First know 
what you want to do, and then do it.” So here, 
before anything can be done, it is necessary for care¬ 
ful plans to be made to show what is wanted, and 
these plans should be carefully studied and every item 
shown in them or described in the specifications should 
be noted. 

Trusting my efforts will prove useful to the young 
and progressive workman who has a desire to become 
a contractor, and that they will aid and assist him in 
bettering himself, and with this hope in view I close 

<&is volume. 




HODGSON’S ESTIMATOR AND CONTRACTOR’S 

GUIDE. 


The student will be expected to read carefully these 
papers before doing any work. His name and address 
will require to be given on each paper. He will be ex¬ 
pected to write up the questions in a neat and intelligent 
manner, using his own language and style, representing 
the answers in such a manner as will be intelligible— 
make all drawings as clear as possible, and wherever it 
can be done render them in India ink. Let each answer 
be original, do not copy either from the instruction paper 
nor from any other source. The paper used may be of 
any kind provided that it is clean and durable. Do not 
attempt an answer until you have thoroughly grasped 
the subject. 

OUESTIONS. 

1. What are the three important things that are to be 
considered in the pricing of all items in making up cor¬ 
rect estimates for builders’ contracts? 

2 . Besides the three important things that enter into 
the consideration of all prices, mention three contingen¬ 
cies that may arise that would considerably affect the 
prices. 

3 . Concerning the question of profit that the contrac¬ 
tors should have when estimating, mention the least 
percentage that should be charged, and method of doing 
so. 


248 


AND CONTRACTOR'S GUIDE 


249 


4 . Upon what should the profit be higher when esti¬ 
mating on certain jobs than others, and give the least 
percentage that should be charged on work costing up 

„ to $ 2 , 500 . 

5 . Mention some of the reasons why the larger con¬ 
tractor can do work at cheaper rates than the smaller 
contractor, and to what should the smaller contractor 
resort in order to protect himself from loss. 

6 . 'Mention the certain fixed charges or provisions in 
making up contracts that must not be overlooked, and 
what should be done with such charges along with the 
percentage of profit. 

7 . Give another very important question that should 
be considered and that enters largely into the cost of 
certain kinds of work that may be included in the esti¬ 
mate. 

8 . Give a description of the different kinds of dis¬ 
counts that are to be taken in consideration in the pricing 
of the several items included in the estimate. 

9 . What should the estimator do in order that he may 
know that he has not omitted anything that should have 
been taken into consideration in framing his estimate. 

10 . Mention the several things that should be con¬ 
sidered and ascertained as near as possible in the first 
place in the pricing of any contract. 

11 . Give detailed descriptions of the five different 
methods of estimating, and the characteristic feature of 
four of these methods employed, and that of the fifth 
method. 

12 . In order to ascertain the method of estimating by 
taking out accurately quantities of materials from the 
plans, wliat branch of mathematics should the estimator 
have a fair knowledge of? 



250 


HODGSON’S ESTIMATOR 


13. Besides taking the greatest care in abstracting the 
quantities from the plans, what document should have 
most careful consideration in every particular during 
the process?

of each of these four figures. 

16. Give rule how to find the area of a iriangle. 

17. Give the rule how to find the area of a triangle 
from the length of its sides, and the example of finding 
the area of a triangle whose sides are 134, 108 and 80 
rods. 

18. Give rule how to find the hypothenuse of a right- 
angled triangle, when the base and perpendicular are

GUIDE TO CORRECT 
MEASUREMENTS 




AUTHORS’ PREFACE 


To ascertain accurately the cost of buildings proposed 
to be erected, and the separate values of the different 
artificers’ work, it is essential that a system of measure¬ 
ment be adopted. When an uniform system has been 
introduced into a country or any district, it gives a 
proper basis for each contractor to figure out his esti¬ 
mate. The present treatise is intended to meet this 
demand by formulating a system which has been practised 
for many years by me in my profession as a quantity 
surveyor and estimator in a large city. The advan¬ 
tages of this system are accuracy and minuteness of 
detail, which give the nearest value possible that would 
be satisfactory to proprietor and contractor. The 
various artificers’ work shall be treated separately, show¬ 
ing the methods of measuring each and making out the 
measurements of same.

(l) Foundations (other than rubble) for walls to 
be measured by the cubic foot where 12 inches thick or 
upwards; and where under 12 inches thick, to be meas¬ 
ured by the superficial foot, stating thickness. Founda¬ 
tions for columns and pillars to be classed separately, 
according to size. The prices shall include materials, 
dressing, and building, but preparing for sole plates to 
be charged separately. 

Thus in the first instance a stone 12'0" long, 2'0" broad,

builders’ and contractors’ guide 


The prices shall include materials, dressing, and 
building, but preparing for sole plates shall be charged 
separately. 

(2) Building of every description—with exceptions 
hereafter stated—shall be first measured as rubble by the 
superficial yard, and classed according to style of work 
and quality of materials. 

The exceptions are: Cube columns and pillars not 
connected with rubble, cornices in one or more leaves, 
anyone of which goes through full thickness of walls, and 
other courses going through full thickness of walls, 
mullions, transoms, tracery, skews, chimney stalks, 
newels, parpend ashlar walls, steps, platts, pavement, 
hearths, shelves, skirtings, border stones, copings on 
walls; and which shall be held to include building and 
laying, and shall not be measured as rubble. 

(3) Two feet shall be the standard thickness of 
building. Walls exceeding that thickness shall be 
reduced to it; and those under two feet thick shall be 
classed according to their respective thicknesses. Thus 
in the first instance a wall varying in thickness at dif¬ 
ferent heights is measured in the following manner: 

Rubble wall above foundation.2-10X47-0X 9-0= 66-5-3 

Rubble wall above 2'10" thickness.2- 6X47*0X10-0= 65-2-6 

Contents of 2'0" work in superficial yards 131-7-9 

These foregoing calculations are divided by 2 to bring 
them to the standard thickness of 2 feet, after being 
multiplied by each other, and then divided by 9 to 
give the contents in superficial yards, thus*

either in length or height. Gable tops and pediments 
shall be taken the average width within the skews by the 
perpendicular height, or in such a manner as will ascer¬ 
tain the net superficial area. 

Thus in the measurement of pediments the half of the 
base by the perpendicular height gives the net superficial 
area, in this instance.

The projections of such continuous cornices, mould¬ 
ings, and belts as are measured for rubble shall be 
reduced to the thickness of the walls with which they are 
connect^ Thus;

Note. —The calculations of the projecting courses to 
be divided by 2 after being multiplied, to bring them to 2 
feet work, the thickness of wall. 

All circular and oriel walls to be measured on the 
outside circumference, and classed to their respective 
thicknesses, in every other respect they shall be measured 
as stated for straight work.

transoms, and tracery to be deducted from the building. 
No deduction to be made for vents, but thin parts of 
walls, such as window bossings, wall presses, and other 
recesses shall be deducted from main walls, and classed 
according to thickness.

METHODS OF MEASURING 


In the former part the rules for measuring the 
different kinds of artificers’ work have been given, and 
now we have to consider the method of carrying them out 
in practice. In doing so .we may state that we do not 
intend to touch upon the quality of materials, nor of the 
component parts which are comprised in their manufact¬ 
ure, but solely to adhere to the elucidation of the method 
employed in measuring the various departments of work. 
A vast amount of valuable information of great assist- 
ance to the estimator can be had from “The Estimator's 
Handbook and Guide” by Mr. Fred T. Hodgson, which 
would be of service in pricing the various items. 

In taking off the quantities from the plans, the same 
method should be carried out, a€ described for meas¬ 
uring completed work, but it is very essential that the 
estimators should have a thorough knowledge of building 
construction and be able to describe minutely and ex¬ 
plicitly every item, so that there may notb~ any ambiguity 
as to the meaning of same. 

The instruments commonly used in measuring the 
various works are, a 6-foot rod, a 3-foot rule, and a 
50-foot or 60-foot tape line. It is necessary also to have 
a book to mark down the measurements—preferably 
one of an oblong shape, and lined off thus, so that it may 
bp easily held in the hand;

NOTES ON THE VARIOUS WORKS 


EXCAVATOR WORK 

The excavator is the person who undertakes to do all 

the digging operations in connection with the building. 

» 

The tool generally used is the common spade, but there 
is often used a large scooped shovel which is drawn by a 
horse, especially where the soil is of a sandy nature. The 
prices per cubic yard for digging operations are regulated 
upon the condition of soil, whether it is hard or soft, and 
the time that would be taken in doing the specified 
quantity. In order to ascertain the cubic contents of exca¬ 
vating work done, it is necessary to find the data of the var¬ 
ious levels of the ground previous to digging operations. 
The site for the proposed building may have a very 
uneven surface, and so it is necessary to reduce the 
elevated parts of the ground to the lowest level, which 
will be to the uniform level of the ground previous to 
digging for the underground work of the building. 
The instrument used for leveling is the Theodolite, 
which stands upon a tripod or three legs. It is generally 
placed in such a position that commands a favorable 
point to take observations of the whole surface, and 
where this is not accessible it has to be moved from 
place to place in order to gain the best available point. 
Within the Theodolite there are two cross films—and 
the center point is that which gives the observation of the 
number of feet as shown on the rod which is held up at the 



148 


13rir. disks' and contractors* guide 



place where the level is to be 
taken. Firstly, however, a 
datum is to be taken of the 
place from which all the levels 
are to be regulated. Thus, 
often the corner of a wall of 
a neighboring house may be 
chosen, and a mark made by 
a chisel upon the wall indicat¬ 
ing the point of vision taken 
Oj while looking through the 
^ Theodolite. The index on the 
' H rod which it strikes is then 
noted in the observation book 
for future reference. When 
all the observatives are taken 
then they have to be regulated 
according to the rise and fall 
of the ground in comparison 
with the datum taken. 

When the levels are taken 
and jotted down in the note 
book, then the calculations 
may be made in the office. 
The surface of the ground may 
be divided off into sections at 
the various points, and taken 
the average depth. Thus the 
various depths are taken and 
calculated on the various sec¬ 
tions of the surface:—

Amount of digging for No. 3 section ... .25-0x16-0x8-0 
Amount of digging for No. 4 section_ 30-0x20-0x9-0 

Cubic yards_ 

This reduces it to the level surface of the ground and 
then the excavator may begin to do any undersurface 
digging that may be required. The digging of same may 
be ascertained in a like manner. 

When all the levels are taken and quantities made out, 
it is necessary to describe the nature of the soil whether 
hard or soft, if the soil is to be wheeled to some part of 
adjacent ground or carted away altogether from the 
location. The excavator then can come to a proper basis 
upon which to regulate his price per cubic yard. 




NOTES ON MASON AND BRICK WORKS 

The term rubble is given to the rough stones that are 
generally used for the backing of walls where there is a 
facing of hewn work, or for walls of buildings where no 
facing is required. Common rubble is not hewn, but only 
shaped to the position it is to occupy in the building, and 
is generally not placed in any regular form. Square 
dressed rubble is hewn on the face to make the surface 
more regular and give it a better appearance. Ashlar is 
stone often used for the facing of walls, and is either 
polished or rock faced. Polished ashlar is generally used 
in the facing of buildings of a costly character, and those 
that are exposed in conspicuous positions to the public 
view. It presents a very pleasing appearance when built 
in regular courses. The thickness of ashlar is in general 
6", and in courses 12" or 13 ,; deep, and is set in mortar 
and jointed with putty. Rock faced ashlar is the 
face hewn rough in the center with a margin wrought 
round each block of stone. This is often adopted in 
buildings where a relief is desired from the plain or uni¬ 
form face in other parts, and it has the effect of giving a 
rustic appearance which is a very pleasing contrast. 
Buildings of a castle or fortress character have very 
often this class of facing adopted in their construction 
which gives an imposing and bold effect to the general 
appearance. Another kind of ashlar is that which is 

termed droved, and derives its name from being droved 

150 


TO CORRECT MEASUREMENTS 


151 


or hewn with a chisel and then placed in its position in 
blocks. Again there is vermiculated ashlar, that has the 
face hewn in a worm-like form in the center of the block 
with a margin of plain dressed or polished hewing round 
same. Again there is crow-toed ashlar which has the 
face done in the form of crows' toes. There are other 
kinds of hewing also adopted in dressing of stone, such 
as scabbled, striped, grooved, fluted and piended. There 
are also other varieties of stone, such as boulder stones 
and whin stones. The system of building with boulders 
has been in practice for several centuries. When 
we recall to mind the great walls that have been built by 
the Romans, notably the one stretching between the 
estuaries of the Forth and Clyde in Scotland, we have 
an example of the very early period in which it was 
adopted. Again when we see the ruins of some of the an¬ 
cient castles or fortresses throughout Great Britain which 
have stood the test of time, and seen the practical pur¬ 
poses which boulder stones have served, we can well 
understand the durability of such material when properly 
built. The boulders are often found on the sides of 
mountains, on the margins of lakes, by the roadsides or 
in the fields. If they are found in the vicinity where it is 
proposed to build, then the expense of quarrying is 
saved, for they are generally on the surface or a little 
underneath the soil. In Scotland this method of building 
with boulders is frequently adopted and in many of the 
ancient towers and castles it may be seen. Although 
often, too, found built in their natural condition, yet they 
may be hewn to meet the requirements of the style of 


152 


builders' and contractors’ guide 


Architecture used. The various kinds of stones have 
certain qualities which make them applicable to some par¬ 
ticular style of building, and boulder stones are well 
adapted for the Baronial style where ruggedness and 
strength are the prominent characteristics. The sizes of 
boulder stones vary from 3 inches to 8 cubic feet, and are 
to be found in different colors, such as grey, blue, green, 
brown, red and several others. The various shades may 
be well adapted to give a pleasing effect to the building 
when placed in certain positions. Boulder stones can be 
utilized for window heads, window sills, window jambs, 
square corners, window arches, chimney-coping, door¬ 
steps, and other parts of the building, if required. When 
white boulder stones are used at corners of walls or at 
window jambs, and filled in with blue whin stones of 
different sizes in courses between, they present a pleasing 
appearance. The boulder stones are set in lime and neatly 
painted with black mortar and white lead in the key- 
drawn joint. Besides being used in the building of houses 
the boulder stones may be utilized with effect in building 
churches, and public buildings where strength and 
solidity are required, and may be hewn to the size and 
shape that may be best suited to the order of Architec¬ 
ture. Many of the dykes or walls that enclose the fields 
or rural districts of Scotland are built with boulder 
stones laid on the top of each other without mortar. 
These are not generally set in any regular order nor 
intended to be always permanent, as they may be removed 
from one position to another as may be required. Whin 
stone is found in different parts throughout Great

Britain, and is of a very hard and durable character. It 
is not easily hewn, but when it is made into regular 
shaped blocks and placed in proper positions in the build¬ 
ing it presents a very neat and pleasing appearance. The 
dressings of corners, windows and doors have generally 
freestone, adapted to give contrast to the whin stone 
facing. Cottages or small houses have often whin stone 
as the facing for the outer walls, and it is very neat in 
appearance, when laid in courses 6 inches deep, and 
jointed with white putty. Churches or castellated build¬ 
ings are also often built of this kind of stone, and it is 
very durable and well suited to withstand the influences 
of the weather. There is also the granite stone which is 
very little used in building and is principally utilized for 
the making of monuments, steps, pillars, columns, piers 
and other requirements. Sometimes the base part of 
buildings is done with this material and may be either 
rough or polished. It is very hard and consequently not 
so easily hewn, but when polished it presents a nice 
appearance, and is very durable. There are some locali¬ 
ties, but very few where granite is to be found. Aber¬ 
deenshire in Scotland is where some of the best quarries 
are to be found, and notably in Aberdeen and Peterhead. 
The former city is called the Granite City, where nearly 
all the buildings are constructed with granite found ip 
the district. There are other kinds of stone that may be 
used for building purposes such as marble, etc. 

In treating of brick, there are two kinds which are 
often adopted in building; the common red and white brick. 
These again may be made smooth, and present a more 


154 builders' and contractors' guide 

finished appearance to the building. Buildings that are 
built with brick and cement mortar are often very 
durable when good material is used, but if the brick be 
of a soft character the building would be apt very soon to 
give way. There are many purposes to which brick may 
be applied, but it is unnecessary to enumerate them. 
Brick is the best material for the construction of large 
chimney stalks and flues, and may be built with the red 
brick outside and white fire clay brick on the inside. 
Brick may be made into any shape by being moulded. 
Thus we have moulded cornices, rounded corners and 
splayed bases. We shall not touch upon the manufacture 
of the brick, as there are processes which would cause 
unnecessary detail. 


NOTES ON CARPENTER AND JOINER WORK 

In considering this subject we would notice the vari¬ 
ous kinds of timber and the practical purposes to which 
they may be applied. The timber that is exposed to the 
weather must be of a harder and more durable character 
than those for inside use, and according to the different 
parts of the work required to be done the timber that is 
most suitable is generally adopted. Thus white pine is often 
used for roofing spars, joisting etc., while American 
Yellow pine is adopted in the finishings, such as doors 
and lining of rooms. It is right to see that all timber be 
free from shakes, sapwood, large and loose knots and 
other imperfections before being used. There are many 
blemishes to be avoided in the choice of timbers, especially 
when they are to be used for very particular purposes. 
The timber must be thoroughly well seasoned, otherwise, 
there may arise several imperfections that will show 
themselves through time in the timber, caused by 
exposure. The timber for safe lintels, beams, wall plates, 
wall straps, dooks, window sashes and cases, frames and 
framing of outer doors are generally of Riga red pine. 
The finishings such as windows and doors are generally 
now done by machinery, whereas all the finishings in 
former times, used to be done by the hand and so a less 
amount of work was accomplished in the same space of 
time than what can now be done by the appliances at 
command. In all the various kinds of Joiner work there 


156 builders’ and contractors’ guide 

are many tools used in their construction, and the manip¬ 
ulation of these require competent tradesmen to put 
together the various parts of the work. Great progress 
has been made in the manufacture of the more intricate 
and ornamental parts in the joiner work of the more costly 
buildings now erected as new designs are being intro¬ 
duced and the methods adopted are carried out with great 
efficiency. We will now consider some of the details 
connected with Carpenter and Joiner works, thus:— 
Joisting are made of different scantlings such as 10X2 
11 "X3', and sleeper joists 3X2 or 4"X2" which are gen¬ 
erally laid on the ground floor and often laid on asphalt. 
Joisting is often placed 18" to centers and cross-keyed 
dwangs are placed between them to give strength to the 
joists over the width of area which they have to cover. 
The joists are often inserted 9 inches into the wall and 
having iron or fire clay shods where there are vents, tc 
prevent the joists from taking fire. At the hearths 
there are bridles into which the joists are inserted, and 
often they are half an inch thicker to give strength for 
insertion of the joists, thus the bridles would be 10"X3" 
for a 10"X2/4 u joist, and would be formed thus:— 



Ficr. 2.7.

On the top of tlie joists the flooring is laid which is 
generally 1thick and in boards 5 or 6 inches in 
breadth or in narrow boards 3" broad. The boards 
are generally feathered and grooved in the joints and well 
nailed, and the overwood well cleaned. The ceiling joists 
do not require the same strength as the floor joists, as they 
have not the same weight to bear, but are only laid on the 
wall head at each end, and the ends of roof spars are 
notched into them and kept tight by the poleplate: thus: 



p l 6.^.8 * 


The balks are the pieces that bind the spars to each 
other on both the sides, and the oxterpieces are pieces 
nailed to the spars and ceiling joists. On the top of the 

spars is the sarking -Ms" thick and the ridgeboard is 

at the top of the spars, and is either rounded on the top 
or having a rounded batten nailed on to form a roll for 
the lead or zinc. Gutter boarding and bearers are placed 
in the valleys between roofs, and often snow staging above 
this again when required. Then there is the facing board 
along the eaves for nailing the eave gutter to. The roof 

lights are composed of top, bottom and end rails also 

astragals for the glass. Louvre-boarded ventilators are 




158 builders' and contractors’ guide 

placed on the roof and may be made to any size as may 
be required. Over the openings in the walls there are 
the beams or safe lintels. They have generally a rest of 
nine inches on each side, and when inserted into the wall 
are rough, but when exposed over any opening they are 
dressed. Beams are made in different lengths, but should 
be specified if in long lengths, as the price will be more 
per lineal foot. Door frames may be described as per pair, 
giving the height of ceiling and the thickness of the brick 
partition in which they are placed. Thus:—one pair 
door frames in 4 Yi" brick partition the ceiling 10' 0" high. 
Those door frames in standard partitions may be measured 
in a similar manner. Or again the frames and lintels for 
doors may be measured by the lineal foot. Partitions 
where standards are used are generally composed of 4"X2" 
standards placed 14" to centers, and having 4X2 runners 
at top and bottom and dwangs in center. 

Windows are generally made 2/4" thick and having 
cases. Windows may be with or without astragals, and if 
having small panes should be specified so, as an extra 
price would require to be charged. Windows may have 
circled or gothic shaped tops, and an extra charge should 
be made for forming same. Windows that have mullions 
or transoms should have the same specified and measured 
by the lineal foot giving breadth and thickness. Where 
spandril boards are, these should be described giving the 
extreme measurement. Windows are generally hung 
with lead or iron weights and strong hemp cord with 
brass faced axle pulleys. They may be hung on both 
sashes or only on one, but must be so specified. Doors

are made of various kinds of timber and different thick¬ 
nesses. Two inches is the thickness of ordinary doors, 
which are generally for the outer doors or inner pass 
doors. Press and closet doors are generally made l 1 /*" or 
lH" thick. The number of panels in doors should always 
be specified and the kind of mouldings in the panels 
described, also whether it is square on the one side and 
mouldings on the other. In measuring bound partitions 
where the glass is in upper portions, the thickness of 
bound work should be taken and classed by the superficial 
foot, all mouldings and copes measured separately and 
astragals describing their size. The wainscoting on 
walls to be described giving the thickness and the mould¬ 
ings and copes measured by the lineal foot. 

The order in measuring Carpenter and Joiner works 
is to begin by taking the rough timbers first, such as 
safe lintels over openings, beams, wall plates, runners on 
brick partitions, sleeper and floor joists, door frames, 
ceiling joists and roof timbers. In taking the finishings 
begin with the upper floor and come downward. Firstly: 
Take all the windows in each room with their finish¬ 
ings, then all the doors with their finishings, and 
then the mantel-pieces and skirtings in each apart¬ 
ment. In the next story down take the same order. In 
the note book then you can see at once where to find each 
item and so have them classified and arranged in the 
completed measurement. After you have taken the 
rough timbers on a piece of paper that you have as a 
draft you may then take all windows with their finishings 
in one place, the doors with their finishings in another 


160 


builders' and contractors' guide 


with all ironmongery and then note these in proper order 
form same as described in Form of Estimate. The com¬ 
pleted measurement should be kept in as near a form of 
order as detailed in the Estimate, as the prices in the 
Estimate can be better applied and placed in order in the 
measurement. 


NOTES ON SLATER WORK 


In many localities slates are not to be obtained, but in 
England and Scotland where there are several quarries, 
the slates are greatly utilized for the various buildings 
that are erected. The Westmoreland slates of the North 
of England and those of the Western Highlands of Scot¬ 
land are chiefly in demand throughout Great Britain. 
Those from Westmoreland are green and of a durable 
character, and give a neat appearance to the roofs, when 
properly bonded. The slates from the western Highlands 
of Scotland are generally blue and can be had in various 
sizes. Slating in Canada is very seldom done, and when so, 
the slates are shipped from a considerable distance. Shin¬ 
gling is the method done generally throughout the Domin¬ 
ion, and when the roofing is painted it has the appearance 
of slates such as are used throughout Scotland. Slating 
makes a very durable and strong material for resisting 
the effects of snow and rain, as well as the sparks from 
fire. Although the prices of slates are much higher than 
shingles or any other material, yet it is to advantage, in 
getting roofs done with them, because of the durability 
and adaptability that they possess. The slates are gen¬ 
erally three fourths square dressed and bored 1 Yz" from 
top, havingS'' of cover at the eaves gradually diminish¬ 
ing to 2" at the ridge and put on with galvanized steel or 
iron nails weighing 12 pounds per thousand. Slates can be 
put on in various patterns and shapes, but where they are 
more intricate than the common mode of slating, it re¬ 
quires considerably more time in arranging and fixing them.

NOTES ON PLASTER WORK 


There are different kinds of material with which plas¬ 
tering is done. There is the common plaster composed of 
haired lime mixed with lime shells, and pure water. This 
after being made into the proper consistency is put on 
the walls and floated with a square piece of wood having 
a handle which is used for the purpose. The first coat of 
plaster is then left to thoroughly dry and then the sec¬ 
ond coat is put on, and when this coat is in a condition to 
receive the third coat, it is then put on and finished in a 
polished manner with white stucco plaster. This is then 
the last coat which completes the plastering of the walls 
in general cases, as three coats finished white makes a 
first class job. The walls then should be in a proper 
condition for receiving paint or any other material that 
may be desired to cover the same. There are also Port¬ 
land and Roman cement which are used frequently in the 
plastering of walls. Then there is stucco or plaster of 
Paris that is used for the cornices and ornaments of the 
building. These can be run or moulded into any shape 
or form as may be desired. There are many kinds of 
ornaments adopted in the cornices. There is the modil- 
lion block, the egg and dart enrichment, the various kinds 
of floral ornaments, the dentil ornament, the patera 
ornament and several others that might be mentioned. 
Center flowers are made in different patterns and in 
various sizes.

NOTES ON PLUMBER WORK 


This work is very important from a sanitary point of 
view and is worthy of great attention being given to its 
study and development. The roofs of buildings have 
generally lead used in the various parts that are exposed 
to the weather such as ridges and piends, valleys and 
round chimney stalks, and these lead pieces, should be 
well batted down and secured from being removed by 
storm. Zinc is also often used in connection with roof 
work, such as ridges and piends, valleys and round 
chimney stalks, etc. The conductors or pipes that convey 
the water from the roofs are of different bores or inside 
diameter, as the requirement demands. At the top of 
these pipes there are boxes or cistern heads in which the 
water is contained previous to its flow down the pipes. 
These pipes may be made round or square, and fastened 
by iron holdfasts or loose ears. At the top of some of the 
pipes where there are projections of plinths there are 
offsets projecting beyond the wall to allow the rain water 
to flow into the pipes. At the bottom there are shoes or 
bends to allow the water to flow from the pipes at the 
ground or there may be heel rests at the bottom for con¬ 
necting at drains. The pipes or bends from sinks or 
jawboxes are often carried to the outside to join the rain 
water pipes. The jawboxes or sinks are generally placed 
in a convenient position next the outer wall, and are 
inclosed often with lining H" thick and having a door in 

163

same for access. The top part or sole board is at the end, 
while the hardwood cope is round the opening of sink. 
The position is thus: 



Inside the sink there is a plug and socket at the top of 
the waste pipe with chain attached, while there is a brass 
grating for allowing the water to discharge into the waste

pipe. There is also an overflow at the top of the sink 
for the water when it rises to a certain level. On the 
waste pipe from sink there is a cesspool, or trap, and a 
brass screw attached to give access for cleaning purposes. 
The water closets are often situated also near the outer 
wall so that the soil pipes may be carried down conven¬ 
iently for discharge to the outside. The soil pipe is 
connected with the horn of closet and has also a bend or 
cesspool with screw for access to same for cleaning. The 
soil pipe is sometimes carried down inside the wall, but 
for sanitary purposes it is better that it be carried outside 
the wall, and having a grating on top for ventilation. On 
the down soil pipe outside the wall there are horns cast 
on for the reception of branch soil pipes from closets. At 
the bottom there are heel rests at connections of drains. 
The thickness of inside diameter of soil pipes is generally 
5" or 4 ^ 2 ". The bath pipes are more complex in their 
construction as often there are hot water pipes to be 
brought from the tanks where the hot water is generated. 
The cold supply pipes to baths, sinks and cisterns, as well 
as to hot water tanks, are brought up from the ground 
and carried through the building to their various places. 
The cold supply pipes to baths are led along to where the 
cranes are situated and the hot supply pipes also to their 
cranes. Then there are the other pipes such as the waste 
or discharge pipes, rod pipes, and fittings for baths. Baths 
may be fitted up with plunge, spray or shower. Hot 
water tanks are generally situated in the kitchen, where 
the pipes for the tanks may be led from the kitchen 
boiler. The revolving pipes are those between the tank 
and boiler. The other pipes from the tank convey the hot 


ICG builders' and contractors’ guide 

water to the bath and sink. The fittings of the tank are 
generally 3 couplings for connecting pipes. The fittings 
for sinks and baths may be either made of brass or 
electro-plate or gun metal. The sanitary condition of 
the building or house depends greatly upon the method 
and perfect equipment of all the parts to the uses for 
which they are intended to accomplish the desired results. 
It is of importance that the water closet fittings and 
arrangement of its position in the house be particularly 
attended to, also the method in which the soil pipe is made 
perfectly air tight, and the connection it has to the drain, 
and exit of the soil therefrom. Ventilation of the soil 
pipe is very essential, and should be done in the most 
thorough method possible. The gasfitter work of a house 
is also of much importance where a supply of gas can be 
readily obtained. The pipe conveying the gas from the 
main is led into the house and connected to the meter 
which has an index that records the number of cubic feet 
consumed, and this may be priced per thousand feet and 
the cost ascertained. The pipes are made of composition 
or block tin and of various diameters or bores according 
to the number of lights required in the various apart¬ 
ments. They vary from V/ 2 " to Y\' in diameter and 
according to the position of the apartment and the number 
of lights in it, the pipes will be led in the shortest method 
possible to save expense. Then there are couplings which 
connect the pipes at their junctions where they branch off 
to the several apartments. Brackets are fitted upon the 
walls or mantel-pieces, and gasaliers from the ceilings. 
These may be had at various prices, and from the plainest 
to the most elaborate design. 


NOTES ON PAINTER WORK 


Beauty and cleanliness, along with good taste are very 
essential elements in the finish of a building. The 
Painter's art is one of great importance in producing 
these when carried out in the most thorough manner. 
Painting may be done with various kinds of material. 
Thus we have oil color, and water color. The oil color 
gives a more durable condition and may be easily washed. 
The water color is of a cheaper material and can be used 
for common purposes. The oil paint can be made into 
various tints according to the class of work that may be 
desired. Harmony of color is very important in painting, 
as a deficiency in this respect displays a want of good 
taste. The work of a good painter should produce the 
highest artistic results. For this class of work the 
Decorator is brought into requisition, who requires to 
devote his time to the study and development of the 
newest and best designs, and produce original sketches for 
the various subjects that may be required. The decora¬ 
tion of churches, halls and public buildings call for the 
skill of the best artists, and this class of work becomes 
very expensive owing to the time required in gaining the 
experience of same, and the great care and taste dis¬ 
played in producing the desired results.

SLATER WORK 

The sketches of roofs are the principal things to be 
taken in note book, and great care must be observed so 
that not one single measurement be omitted to be jotted 
down, otherwise the contents cannot be ascertained. It 
is advisable that the sketches be carefully examined for 
this purpose before coming off the roofs. The contents 
of area of roofs may easily be obtained by dividing the 
various parts into triangles, parallelograms or squares, 
according to the shape of the roofs. The pointing of 

raggles and skews may be taken also when upon the roofs 

* 

and jotted down, and any other work done by slater.

PART II 


Tables, Rules and Memoranda for Obtain¬ 
ing Quick Results in Measurement of 
Areas, Solids and Contents 


PRACTICAL MEASUREMENT OF GEOMET¬ 
RICAL AREAS 

In the following series of problems it will be shown 
how to find the area of any geometrical figure, without 
any calculation whatever, by simply drawing a few lines 
(only two or three in many cases) and then taking one 
measurement. The problems are supplemented by notes 
explaining how to apply the methods to large areas, the 
final measurements being taken on a suitable scale when 
the area is being found from scale drawings. 

(l) Given any rectangle 
and one side of another rect¬ 
angle; to complete the latter 
so that the two areas may 
be equal. (See Fig. l). Only 
one construction line is neces¬ 
sary to solve this problem. Let A B C D (Fig. l) 
be the given rectangle, and D E (marked off on AD, pro¬ 
duced) the given side of the other rectangle. Join E C, and 
produce it to meet A B, produced, in F. Then B F is 
the other side required to complete the other rectangle. 









200 


builders' and contractors' guide 


In other words, the length B F multiplied by the length 
D E exactly the same result as multiplying A B by A D, 
which, of course, gives the area of the rectangle ABC 
D. A very important use is made of this result in 
Problem 3. It may be stated that when a terminated 
straight line is extended or lengthened, this is called 
“producing" the line, and the line so treated is said to be 

“produced." 

(2) Given any square 
and one side of a rectan¬ 
gle; to complete the lat¬ 
ter so that the two 
areas may be equal. 

This is identical with 
Problem 1, since a square 
may be considered as a rectangle. 

(3) To find the area of any rectangle. (See Fig. 2). 

This is a very important problem, since all the areas 
are reduced to rectangles in this series. Take, as 
example, the rectangle A B C D (Fig. 2). Produce one 
side, as A D, and mark off D E, one inch long. Join E 
C, and produce it to meet A B, produced, in F. Then 
measure B F to obtain the required area—that is, find the 
number of inches in B F and call them square inches. 
The reason for this is that the area of the rectangle A B 
C D is equal to B F times D E (see Problem l), and D E 
has been made one inch by construction; therefore the 
required area equals B F (in inches) times one. Notes— 
If, by using a line one inch long (D E in Fig. 2), the 
intersection of lines at F, which denotes the area, become 







TO CORRECT MEASURE M EN TS 


201 


very oblique and consequently vague, a two-inch line may 
be used instead at D E, and thus obtain half the area at 
B F; or D £ may be three inches, and B F multiplied by 
three to find the required area; or D E may be four 
inches, and B F multiplied by four; and so on. Again, 
for large surfaces, or in scale drawings, if D F (Fig. 2 ) 
is made one foot, the number of feet in B F must be 
called square feet, it being only necessary to remember, 
in this case, that any odd inches in the “area line” (B F) 
do not represent square inches, to obtain which it is 
necessary to multiply 
by twelve. Further, if / 

D E is made one yard, / \ 

the resulting area will / \ 

be in square yards, in /_ \ 

which case any odd feet F,c 3 

in the “area line” must be multiplied by three to con¬ 
vert them into square feet, and any odd inches by thirty- 
sixth to convert them into square inches. 

(4) To find the area of any square. 

This is solved by Problem 3, treating the square merely 
as a rectangle. Note—In the case of a square, the line B 
F (Fig. 2) is always the square of A B, and the problem 
may thus be used to obtain rapidly the square of any 
awkward number, fractional or otherwise. 

(5) To construct a square of any given area. (See 
Fig. 3.) 

Draw a line and mark off on it A B one inch long (see 
Fig. 3) and B C (in the same direction) equal to the 
required area—that is, make B C as many inches long 




202 


builders' and contractors' guide 


as the area contains square inches; if, for example, 
the area is to be three and five-sixteenths square inches, 
make B C three and five-sixteenths inches long. Now 
describe a semicircle on A C, and at B erect a perpen¬ 
dicular to meet the curve in D. Then B D is the side 
of square which will contain the given area. Notes— 
This method does not break down when the area con- 
- tains awkward fractions, but is quite as easy and cor¬ 
rect for fractional areas as for simple cases. A B 
(Fig. 3) must always be one inch if the area is in 
square inches. If, however, the area is given in square 



feet, use a line one foot long at A B, and if there are any 
odd square inches in the area, they must be divided by 
twelve before being included in the “area line” (B C). 
Suppose, for example, a square is required containing 
eight square feet, 102 square inches. Now 102 divided by 
twelve is eight and one-half; therefore make A B one foot, 
and B C eight feet, eight and one-half inches. Then B D is 
the side of the required square. If the area is given in 
square yards, etc., make A B one yard, and divide the 
odd feet in area by three and the odd inches by thirty-six. 

(6) Gi veil one side of a rectangle; to construct the 
figure so as to contain any given area. (See Fig. 4), 





TO CORRECT MEASUREMENTS 


203 


A B (Fig. 4) is made equal to the given side. Pro¬ 
duce it and mark off B C equal to the given area—that is, 
if the area is to be, say, three and one-quarter square 
inches, then B C must be made three and one-quarter 
inches long. Draw perpendiculars at A and C, one on 
each side of the line. Mark off A D on the perpendicular 
at A equal to one inch. Join D B, and produce it to meet 
the other perpendicular in E. Then C E is the required 
side of rectangle. Note—A D must always be placed at 
the end of the given side, not at the “area” end of the 
line. A D must always be one inch if the area is given 
in square inches; if it is 
given in square feet or 
square yards, see note to 
Problem 5. 

(7) To find the area 
of any rhomboid. (See 
Fig. 5). 

Take, as example, the 
rhomboid A B G H (Fig. 

5). From A and B draw perpendiculars to meet G H (or G 
Ii produced) in C and D. Then the rectangle A B C D 
equals in area the rhomboid A B G H. Proceed to find 
the area of the rectangle, and consequently of the 
rhomboid, as in Problem 3. D E is made one inch, and 
then, B F being two and one-half inches, the area of the 
rhomboid is two and one-half square inches. 

(8) To find the area of any rhombus. 

Proceed exactly as in Problem 7. 

(9) To find the area of any four-sided figure with 







204 


BUILDERS'' AND CONTRACTORS* GUIDE 



C A 


two parallel and two non-parallel sides (trapezoid). (See 
Fig. 6). 

Through the middle 
points of the non-parallel 
sides draw perpendiculars 
to the parallel sides (or the 
parallel sides produced), 
and thus obtain a rectangle 
equal in area to the trape¬ 
zoid. In Fig. G. 

(10) To find the area of any triangle. (See Fig. 7.) 

Take, as example, the triangle ABC (Fig. 7). 
From one angle C draw a perpendicular C D to ti e 
opposite side A B; bisect this perpendicular by a line 
parallel to A B. From A and B draw perpendiculars to 
meet this bisecting line in E and F. Then the rectangle 
A B E F equals the triangle A B C in area. Again, by 
Problem 3, A G being 1 in., F H gives the required area; 
in this case it is 2^in. Notes:—Any of the three sides 
of a triangle may be —® 
taken as '“base,” ac¬ 
cording to conve¬ 
nience, and the “alti- ^ 
tude” measured 
perpendicularly from 
the base to the oppo¬ 
site angle. A rect¬ 
angle can then be 
constructed with the same base and half the altitude, 
or half the base and the same altitude. In an irregular

205 


triangle, therefore, there are at least six different 
rectangles, any of which can be used to find its area. 

(11) To find the 
area of any irregular 
four-sided figure (tra¬ 
pezium). (Fig. 8). 

Take, as example, 
the irregular quadri¬ 
lateral A B C D (Fig. 

8). Draw one diago¬ 
nal A C; draw perpen¬ 
diculars to this diagonal from the other two angles B and 
D, and through the middle points E and F of these perpen¬ 
diculars draw parallels to the diagonal A C; and, lastly, 
through the extremities A and C of the diagonal draw 
perpendiculars to it to meet these parallels in G If J K. 
Then the rectangle G H J K equals in area the irregular 
figure A B C D. Now proceed by problem 3 to find this 
area. K L (Fig. 8) measures 2iV in., therefore the area 
of A B C D is 2iV sq. in. 

(12) To find the area of any regular hexagon. (See 

Fig. 9). 

The hexagon and the 
octagon (Problem 13, Fig. 
10) lend themselves to very 
neat special solutions; they 
could, of course, both be 
F treated by the general meth¬ 
od for regular polygons 
given in Problem 14 (Fig. ll). Let A, B and C

be three alternate angles of the hexagon, as in Fig. 
9. Join A B and produce indefinitely. Produce also the 
two sides which are at right angles to A B, as A E and B 
D (Fig. 9). Through C draw a parallel to A B to meet 
the two last produced lines in E and D. Then the rect¬ 
angle A B D E equals the hexagon in area. Again 
applying Problem 3, B F measures nearly 2 in., and 
therefore the hexagon in Fig. 9 contains 2 sq. in. nearly. 
Note:—To find the area of large hexagonal surfaces, 
simply multiply the two lengths A B and C G (Fig. 9) 

together. 

(13) To find the area 
of any regular octagon. 
(See Fig. 10). 

It can be readily 
shown that in any regu¬ 
lar octagon the area of 
the rectangle made by joining the extremities of two 
opposite sides is exactly half the area of the octagon, 
as A B C D (Fig. 10). Hence the following method 
for finding the area. Produce two opposite sides until 
their length is doubled; thus D E and C F are made equal 
to A D and B C. Join E F, and then the area of the entire 
rectangle A B F E will equal the area of the octagon. 
B G, obtained by Problem 3, measures 1J4> in., conse¬ 
quently the octagon contains 1% sq. in. Notes:— 

For large octagonal surfaces multiply twice the length 
of the side by the direct distance across from side to side. 
The area of any even -sided regular polygon can be found 
a* in Fig. 10 by making A E and B F each equal to a

quarter of the total boundary. For instance, in a duo- 
decagon (twelve sides) A D and B C must be made equal 
to three sides. 


(14) To find the area of any regular polygon. (See 
Fgi. 11.) 

Produce one of the sides until the total length equals 
half the perimeter or boundary (see note at end of Prob¬ 
lem 14). In Fig. 11 the polygon (pentagon) has five sides; 
therefore one side, A B, is extended to C, so that the 
whole line ABC equals 2 
sides. Now draw a parallel 
through O, the center of the 
figure, to meet perpendicu¬ 
lars from A and B, in E 
and D. Then the rectangle 
A C D E again equals the 
given figure in area. The 
length of A F, found by 
Problem 3, is \ Y\ in.; the 
area of polygon is there¬ 
fore 1 : /a sq. in. Notes:—To make B C (Fig. ll) equal 
to half the boundary, proceed in this way: Mark G 
the point directly opposite to A. Then with the 
angle II as center, swing G round until it is in a 
line with the next side (B H) at K; then go to the next 
angle B and swing K round again until in a line with the 
next side at C, and so on. In Fig. 11 no more swinging 
round is necessary, but for a greater number of sides the 
operation must be continued until half the boundary has 
been unwound, as it were, into a straight line. To find 







208 


builders' and contractors' guide 



the center of any regular polygon with an odd number of 
sides, draw a line from any angle to the middle point of 
the opposite side; this line contains the center, and if 

another angle and side are similarly 
treated the required center is the 
intersection of the two lines (dotted 
in Fig. 11). Of course, if the 
number of sides is even, simply 
join opposite corners twice. 

F,aJ2 (15) To find the area of any 

irregular figure with more than four sides (See Fig. 12). 

If the number of sides is even, divide the area into 
quadrilaterals, and find the area of each quadrilateral as in 
Problem 11, and then add these areas; if odd, divide it 
into quadrilaterals and one triangle, as indicated by dotted 
lines in Fig. 12; treat the former by Problem 11 and the 
latter by Problem 10. This method is far less confusing 
and consequently more reliable than reducing the whole 
figure to one triangle equal to it in area (on the principle 
of triangles of equal base 
and altitude being equal). 

Moreover, the results will 
be more correct in the long 
run. 

(16) To find the area of 
any circle. (See Fig. 13). 

On the diameter A B

(Fig. 13) construct an equilateral triangle A B C;

209 


from D and E draw perpendiculars to meet the diam¬ 
eter produced in F and G. Then the rectangle F D 
E G equals the circle in area (see note), and D H equals 
area of circle in square inches as before. Note: The 
length D E (Fig. 13) is generally accepted in staircase 
work, handrailing, etc., as being equal to half the circum¬ 
ference of the circle. As a matter of fact, half the cir¬ 
cumference equals 3.141592, etc., times the radius of the 
circle, while the length B C equals 3.154705, etc., times 
the radius, showing an error of .013113 too much; so 
that the results obtained by the preceding method are a 
little over 2-5 per cent in excess of the actual areas, or an 
excess of .00416 in. (about 1-250 in.) to every square 
inch. This will be near enough for most practical pur¬ 
poses, but where greater accuracy is required the fore¬ 
going figures are taken in order that the excess may be 
subtracted from the result obtained. 

(17) To find the area of any sector of 
a circle. (See Fig. 14). 

The most practical method of solving 
this problem is to find what part of the 
whole circle the sector ABC (Fig. 14) represents; 
this can be done by measuring the angle ABC and 
comparing it with 360°. For instance, 30° is one- 
twelfth of 360°; 36°, one-tenth; 40°, one-ninth; 45°, 
one-eighth; 60°, one-sixth; 67/4°, three-sixteenths, 
etc. In Fig. 14 the angle is 120°, or one-third of 360°. 
Now construct a rectangle equal to the whole circle 
by Problem 16 (Fig. 13), and then take off the part 
required. In the case given in Fig. 14 it will be neces- 

14

sary, after obtaining the rectangle for the whole circle, to 
take one-third of the rectangle as the required area of the 
sector A B C. 

(18) To find the area of any segment of a circle. 
(See Fig. 15). 


V7X 



When the segment ABC is less than a 
semi-circle, as in Fig. 15, find the area of the 
whole sector A B C D, of which it forms a 
part, as in Problem 17, and then subtract the 
area of the triangle A B D, which is found by Problem 
10. If the segment is more than a semi-circle, find the 
area of the whole circle as in Problem 16, and then sub¬ 
tract the small segment not required. 

(19) To find the area of any surface bounded by 
straight lines and circular arcs. (See Fig. 16). 

Join the extremities of the arcs to the centers from 
which they are struck when these centers are within the 
limits of the area being measured; when the centers are 
outside the area simply cut off the arcs 
by their respective chords. Then treat 
the separate portions as an irregular 
polygon (by Problem 15), and sectors or e 
segments of circles (by Problems 17 and 
18). Suppose, for instance, such an area 
as shown shaded in Fig. 16 is to be meas¬ 
ured. A is the center of the circular corner, 
the segment on B C is at first included for convenience, and 
the area of the whole triangle ABC (found by Problem 
10) is added to the areas of quadrilaterals A B D E and A 
CFG (found by Problem 11) and the area of the sector

AEG (found by Problem 17). Finally, the segment B C 
(found by Problem 18) is subtracted. It is possible by a 
little manipulation to treat any area in a similar manner. 

(20) To find the area of any ellipse. (See Fig. 17). 

On one side of the minor axis A B (Fig. 17) describe 

a semi-circle A B D, and on the other side construct an 
equilateral triangle A B C; tangent to the semi-circle 
draw F G, parallel to the minor axis A B, and on the 
same side of the latter another parallel through the vortex 
H of the ellipse; produce the sides C B and C of the 
equilateral triangle to meet the tangent to the semi-circle 
in F and G; through F and 
G draw perpendiculars to •! 
meet the minor axis pro- * 
duced, and the parallel 
through the vertex in J, K, 

L and M. Then the area 
of the rectangle J K L M 
equals the area of the ellipse 
subject to the slight discrepancy referred to in the note 
at the foot of Problem 16. Therefore, to find the area 
of the ellipse find the area of this rectangle K M by the 
method shown in Problem 3. 

(21) To find the difference between any two geomet¬ 
rical areas. 

Represent each area by a single line as shown in the 
preceding problems, and then apply the “area lines” one 
over the other to discover their difference. 

(22) To reduce any geometrical area to a triangle of 

equal area. 









212 


BUILDERS* AND CONTRACTORS* GUIDE 


Reduce the area to a rectangle by the preceding prob¬ 
lems, then give the triangle the same base and twice the 
altitude of the rectangle, or twice the base and the same 
altitude. 


(23) To reduce any geometrical area to a square of 

equal area. (See Fig. 18). 

Reduce the area to a rectangle 
by the preceding problems. Then 
draw a line and mark A B equal to 

the long side and B C equal to 

• 

the short side of the rectangle (see Fig. 18). Describe 
a semi-circle on A C, and at the juncture B of the two 
sides raise a perpendicular to meet the semi-circle in D. 
This perpendicular B D is the side of the required square. 





Abstracting 


In abstracting , the items (amount and description) are 
taken from the dimension sheets, and arranged in the 
proper order in which they will afterwards appear in the 
bill. It is usual to abstract one trade at a time, com¬ 
mencing each on a separate sheet of paper, headed with 
the name of the trade. Leave plenty of room between 
the items on the abstract paper, as crowding leads to con¬ 
fusion and mistakes. 

A general method in abstracting, in each trade, is to 
take the cubic items first, the superficial items next, then 
the items measured “run,” and finally the numbers, 
beginning in each case with the items of least value. 
Each item as it is abstracted, is crossed through with a 
vertical line | ? and when all the items have been taken 
from a single dimension sheet a tick V is placed at the 
bottom. 

In taking the description of items from the dimen¬ 
sion sheet, they should be faithfully copied without altera¬ 
tion, except when extremely long, in which case.a portion 
only may be written with a reference back added (as 
“etc., in sheet”). The abstract should be checked by 
a second person, who ticks the items on the dimension 
sheet and abstract in red ink as he proceeds. 

After all the items iiave been abstracted, each class 
should be totalled, the deductions subtracted, the averag- 

213 


214

ing done if required, and the resulting figures are those 
to transfer to the bill. 

Excavator.—Abstract in order all excavations, after¬ 
wards taking the concrete, etc. To reduce feet to yards, 
divide superficial items by 9, and cubic items by 27. 

Drainage.—Commence with the smallest sized drain, 
first taking the item requiring the least excavation; follow 
in order with other depths and larger drains. 

Bricklayer.—Make four columns, as under :—

and abstract in these, walls of any thickness, e. g. 84 feet 
superficial of 1 or 134 brick wall would be put in their 
respective columns, while 62 feet of 2^2 brick wall would 
be abstracted as 62 feet of 1 brick wall and 62 feet of 
1/4 brick wall. 

If 48 feet superficial of 234 brick wall had to be 
abstracted it would appear in the V/z brick column as 48 
feet, and again as 24 feet. The first item of 48 feet 
equals 1/4 brick thick, leaving 48 feet of Va brick wall to 
be abstracted, which is done by halving the amount, thus 
obtaining 24 feet of 134 brickwork, which is equal to 48 
feet of Ya wall. 

All other thickness walls could be abstracted in one or 

✓ 

other of the columns by proceeding in the same way. 

When all brickwork is abstracted, total the columns, 
subtract the deductions, reduce the 1 brick wall to 134

Facings and other items will follow. 

Mason. —Separate the different kinds of stone, with 
their labors. 

Tiler or Slater.—Take chief item of slating or tiling 
first, dividing total amount by 100 to reduce to squares. 

Carpenter.—Abstract in the usual way, taking cubic 
items first, following with the superficial, runs, numbers, 
and, lastly, any “fixings only” to ironwork. In the runs 
take the smallest sized pieces first, as 2X3, then 3X4, and 
so on. 

Joiner and Hardware. —Separate the various kinds 
of wood, first taking all the pine. Commence with 
floors, dividing by 100 to obtain the number of squares, 
then skirting, sashes and frames, doors, framings, sundries 
and lastly stairs. Follow with the hard woods, as 
mahogany, teak, oak, etc., finally the hardware and fixing. 

Iron-Work. —Take wrought iron first, the cast 
iron afterwards, bringing all to weight in cwts. Wrought 
iron and rolled iron weigh 480 lbs., and cast iron 450 lbs., 
per cubic foot. Consequently 1 foot superficial of T' 
thickness wrought iron would weigh 40 lbs., and cast 
iron 37/4 lbs. Provide columns for various thicknesses 
of iron to be abstracted, and having totalled each, reduce 
all to their equivalent in l" iron; then multiply by 40 or 
37/4 for W. or C. I. 

Plasterer. —Take plastering to ceiling and walls first, 
afterwards the cement work. Divide by 9 to reduce to 
yards superficial. 


21G builders' and contractors' guide 

Plumber.—Include in one item all lead in flats, gut¬ 
ters, and flashings (but lead in secret gutters and stepped 
flashings would be abstracted together to form another 
item). Make columns for 4-lb., 5-lb., 6-lb., and 7-lb., 
lead, under which enter the various squared dimensions; 
multiply the totals by 4, 5, 6, or 7 respectively, and add 
the same together. This gives the total weight in lbs., 
which is then reduced to cwts. 

Take all labors after the lead, and follow with the 
internal work, as pipes, W. C.'s, baths, etc. 

Gasfitter.—Pipes, beginning with the smallest, after¬ 
wards the fittings, etc. 

Hot-water Engineer.—The same order would apply 
as for “Gasfitter." 

Bellhanger.—Bells first, and sundries afterwards. 

Painter.—Superficial items first, dividing by 9 to 
reduce to yards; then the “runs" and numbers. 

Glazier.—Take glass of least value first, arranging 
the squares in their order of “under 2 feet," etc., com¬ 
mencing with the smallest. After glass, abstract any 
labor to that glass before proceeding to another variety. 

Paperhanger.—Although a piece of English paper is 
supposed to be 12 yards in length, it is seldom found to 
measure more than 11 yards; the width is 21", conse¬ 
quently a piece contains about 58 ' superficial. Abstract 
the items, add t to allow for waste in matching pattern, 
etc., then divide by 58, which gives the number of pieces; 
any amount over a piece to be counted as a full piece. 
American and French papers only measure 18" wide, and 
are about 9 yards long, containing 40superficial; 


TO CORRECT MEASUREMENTS 


217 


therefore to obtain the number of pieces divide by 40 
instead of 58. 

The totals of abstract on completion should be checked 
by a second person, in order to avoid mistakes being inad¬ 
vertently made and to ensure that everything is correct.

Billing 


Billing is the operation involved in transferring the 
totals of the various items from the abstract to the bill 
form, in order to enable them to be priced, and to obtain 
an estimate of the cost of the intended work. 

The order of billing should follow the order of 
abstract, if that has been prepared as before explained. 

In large contracts each trade should have a separate 
bill, which should be headed with its name and number. 
In smaller works all the trades are included in one bill. 

It is usual to give a description of the material to 
be employed by each trade at the heading of its bill 
before taking the items, the total estimated amount 
of which is carried to a summary placed at the con¬ 
clusion of the bill. 

V 

\ 

A bill form is ruled as under:— 





cube, 

Vino 

unt 

of 

sup 

it 

em. 


or 




run. 


Description of item. 


$ 


If the total amount ot an item in the abstract is an 
odd, 6" or over, it would appear in the bill as a foot, but 
if under 6" it is entirely ignored, e. g. 38'7'' would be billed 
as 39"', while 26' 2" would be taken as 26'. This also 
applies to other items, as any amount of half a yard or 
over of painting or plastering would be taken as a yard. 

236 












TO CORRECT MEASUREMENTS 


237 


In slating or tiling the feet would be billed as 5, 10, 
15, 20, etc., parts of 5 feet being called 5 feet, and in 
lead, billed at per cwt. the lbs. would be taken as 7, 14, 
or 21. 

The first in order of the bills is Known as the Prelimi¬ 
nary Bill, which contains particulars from the conditions 
of contract and specification which may influence the 
amount of the tender, perliminary works, and provisional 
items. This bill does not pass through the operations of 
“taking off” and abstracting. It is impossible to give 
exact items that would appear in the above bill, as the 
conditions vary in different cases. A few items, how¬ 
ever, that are found in most contracts may be given, such 
as:— 

“The building to be completed and fit for occupation 
by (mention date) under a penalty of $— per week as 
liquidated damages, delays caused by frost and strikes 
only excepted.” 

“Payments may be made to the contractor at the rate 
of 75 per cent, of the value of the work executed, an 
additional 20 per cent, at completion, and the other 5 
per cent, six months from that date. 

A priced copy of the bill of quantities to be deposited 
with the architect when signing contract.” 

“Provide water for the use of the works, and pay all 
lees connected therewith.” 

“Insure the building for two-thirds amount of tender 
in an office approved by the architect.” 

“Give necessary notices to all authorities, supply 
required drawings, and pay all fees.” 


238 


builders’ and contractors’ guide 


“Provide all scaffolding and tackle for the use of the 
works.” 

“Provide a suitable office where directed, for clerk 
of works, also light, fire, and attendance.” 

“Provide watching and lighting as required.”

While the foregoing does not pretend to give all the 
items that may be required, it offers to the measurer some

hints as to what is required, in a general way, for 
domestic buildings. For factories, stables, barns, ware¬ 
houses, public buildings, churches, schools, railway sta¬ 
tions, and similar work, a more elaborate list would be 
required, but the workman should be able to find all the 
items in the specifications prepared for the work under 
consideration, and if he is thorough he will add to the list 
as given above such items with their cost, as he goes 
over them when taking off the quantities. 

The reader of this book, should also obtain a copy of 
Hodgson’s Estimator and Contractor’s Guide; which is a 
companion book to this. This one gives methods of 
computing quantities, the Contractor’s Guide shows how 
to price them. So it will be seen that the two books 
should go together.
